Windows / Re: Delayed Write Failed

Coalesce Disk Writes only became an option in the last couple versions...maybe v4.1.5 at the earliest.

1.What version of qBitTorrent?

2.Did you try also with completely new/default qBitTorrent settings?

3.Try enabling/disabling Coalesce Disk Writes in qBT's advanced settings?
NCQ may not be working properly on that drive and qBT is the only thing aggressive enough with mad numbers of little writes to trigger it.

Windows / Re: I have no idea what value to set for maximum active uploads.

The Azureus U/L settings calculator suggests too-high connection limits both globally and per torrent.
The max upload slots per torrent is often far lower than max connections per torrent, which doesn't work well while seeding.
It lacks global max upload slots to prevent uploading painfully slow per peer (per upload slot to be precise) when there's many busy torrents.
Since it lacks a max active seeding torrents, it's another clue that the settings are overwhelmingly for maximizing download speeds not seeding.

Seeding torrents don't need to connect to other seeds on the same torrent.
Also, it's a little rude as a seed to connect to 40+ peers at once...but only upload to 4 of them. Better to limit max connections per torrent in that case to no more than about 15 if max upload slots per torrent is only 4.

Each upload slot (1 upload to a single peer) has a minimum speed to function properly -- because it sucks to be connected to a seed and it's either not uploading anything to you or only does so at 0-5 KiloBYTES/second.
This forces global upload slots to be no more than about 1/5th (5 KB/sec) of max upload speed -- but I recommend 1/10th instead (10 KB/sec per peer) for much better performance.
With a max upload speed of 100 KB/sec, that means a max global upload slots of 10 -- so each gets ~10 KB/sec.

If a seeding torrent isn't uploading, it's not really active.
So each active torrent needs to be uploading to at least 1 (preferably 2 or more!) other peers.
That means max active torrents and also max seeding torrents should be no more than half the max global upload slots.

For the example of 100 KB/sec max UL speed with 10 max global upload slots, max active torrents could be as high as 5.
Of those 5 active torrents, I wouldn't recommend more than 1 or 2 max downloading torrents at a time so at least 3 seeding torrents can be constantly uploading.

Max connections, upload slots, and active torrents don't scale linearly with upload speed increases -- if anything, increasing the max active torrents means max connections and upload slots PER torrent must go down to prevent overloads.
Having 100 max connections per torrent might work great if there's only 1 active torrent, but if there's 20 or will suck.

Better to upload a lot of torrents to only a few peers each -- and let those few peers share with other peers on the same torrents...than try to upload to everybody at <5 KB/sec each.

That it happens with so few torrents, happens randomly, and ram/cpu usage at the time is unknown makes it sound like a nasty bug just to localize a root cause. :(

Vuze and BiglyBT also have a limit to not start more than "X" number of extra torrents when speeds are low.

Windows / Re: Confused with upload settings
« on: September 18, 2019, 04:26:56 PM »
If you or anyone sharing the internet connection are experiencing slow web surfing (which probably isn't using a LOT of bandwidth itself, other than video streaming or downloading from websites) while qBitTorrent is running...

You may want to set speed limits in qBitTorrent slightly below the max speeds of your connection.
Also try lowering max half open connections in advanced settings.

...But it can also mean your ISP's local node is overloaded, especially during peak weekday evening hours.

I use Scheduler in both qBitTorrent and uTorrent to automatically use much lower max speeds during 5-11 PM hours.

It's almost certainly a qBitTorrent to fix it, qBitTorrent's developers will probably need to know what triggers it.

1.How many torrents do you have loaded in qBitTorrent? (I'd be far more troubled if this happens with <20 torrents total than 1000+!)

2.Are any "missing" in the display at the start? (another possible bug that may be making this one worse.)

3.Around the time this is happening, how much ram is qBitTorrent using? (possible ram overloads?)

Seeding torrents do not connect or at least don't STAY connected to other seeds.

There may be more problems with qBitTorrent with regard to seeding/uploading, but I cannot say how/why without more information.

I don't know the nature of your internet connection -- whether it's a "hostile" ISP that mangles BitTorrent traffic, through a proxy/VPN that prevents or at least poorly handles UDP traffic, or using wifi to your router (which often has severe issues with many connections at once.)

It is ODD that your ubuntu torrent screenshot shows ZEROS for DHT, PEX, and LSD -- this further supports my belief that there is some connectivity issue/s that your end has. DHT uses UDP packets, LSD uses multicast (which almost no ISP supports) or possibly UDP packets as fallback, PEX requires existing connections to peers and/or seeds to do anything.

I can't tell from the screenshot of 0 (1) seeding torrents if they're flagged private and/or on a private tracker, which causes extreme connectivity issues in their own right.

Do you get uTP peer and seed connections at all, (which require UDP packet support) even on downloading torrents?

Windows / Re: Any changes in settings after moving to SSD?
« on: September 17, 2019, 09:46:02 PM »
Running qBitTorrent on a SSD is not a problem -- the OS is certainly far more aggressive than qBitTorrent in writing to the SSD multiple times per minute.

Even strictly seeding from a SSD is not an issue, since that's entirely reads rather than random writes for the torrent.

After qBitTorrent v4.1.something (definitely v4.1.5 and later), qBitTorrent even uses much bigger sequential writes to drives to make downloading to a SSD not nearly as nasty as it used to be.

Newer SSDs made in last 3+ years can handle magnitudes more writes than they used to, and the higher capacity the SSD the less any individual section gets written to due to decreasing odds of targeting that 1 spot and wear leveling. Many can handle 100's of TeraBytes of writes, some can handle >1 PetaByte of writes.

Windows / Re: No upload speed when seeding
« on: September 17, 2019, 09:38:51 PM »
A few ISPs used to use Sandvine equipment to selectively disconnect seeding torrents to almost completely prevent them from uploading.

You need to watch when a torrent finishes downloading to see if all the peers on the torrent disconnect, because that will at least explain the no uploading bit while a seed. (but not why that happens)

1.Is peers disconnecting happening on private tracker/s?

2.Or does it also happen on poorly-seeded public torrents?

Windows / Re: 1 seed, many peers, no traffic
« on: September 16, 2019, 07:14:24 PM »
qBitTorrent counts as peers ANY ip address ever seen, reported, or "rumored" to be on that torrent -- this can include peers that are now seeds and even get counted as both.
Trackers tend to only count as peers the peers that have announced to them in the last hour or 2.

Fake peers may be the cause...or peers that quickly change their ip address and get reported many times.

Also, you're not connecting to the peers because your qBitTorrent is probably blocked/firewalled -- possibly in multiple ways!
Software firewall, router+LAN ip address use, ISP that blocks incoming connections and/or tries to cripple/block BitTorrent traffic in general, proxy/VPN that prevents incoming connections...may all be to blame.

qBitTorrent is improving if you see even occasional better results than uTorrent.
I pretty much never did with similar or identical torrents loaded, and this despite doing pretty thorough tests in that regard.

« on: September 14, 2019, 07:46:48 PM »
There is also a blacklist of apparently bad trackers, which isn't explained why they are bad.
Many big and small trackers have ceased to exist, but many torrents continue to include them. In BitTorrent clients that support a tracker blacklist, tracker announces to those trackers are not attempted.

It's been requested a few times...

Multi-tracker EDITING nonexistent!
Add way to mass update announce url
change properties of multiple torrents
Edit tracker for selected torrents and other features request
Is there a way to Edit all trackers simultaneously ?? Thanks..
Add tracker to multiple torrents
Feature: Tracker manager: bulk add/remove/edit outdated tracker/s of all torrents
Batch-edit tracker URL on multiple torrents in the same time
[Wishlist] Tracker List sorting
[Wishlist] Default Tracker List
[Wishlist] Add the ability to edit trackers in torrent add dialog

...but the only way to speed up the process would be to join qBitTorrent development and make the code to do that, because it seems the very few remaining qBitTorrent devs are still busy trying to fix show-stopping crashes that happen to a few people.

« on: September 13, 2019, 04:28:29 PM »
The dreaded (largenumber) peers amount probably happened due to past peers never reported to your qBitTorrent end as now-seeds or gone-for-good.
