Qbittorrent 4.0 Windows High Cpu Usage, Process Won't Die After Exiting #7763

Closed CeruleanSky closed 6 years ago

CeruleanSky commented 6 years ago

qBittorrent version and Operating System

Qbittorrent 4.0..0 x64 - qbittorrent_4.0.0_x64_setup.exe

What is the problem

Qbittorrent has high cpu usage. It appears to be one thread. After exiting, while most of the windows are destroyed, the thread continues to run forever.

The program does not appear to be frozen.

What is the expected behavior

Qbittorrent to exit after a few seconds or minutes.

Steps to reproduce

Open Qbittorrent. Close Qbittorrent.

Extra info(if any)

Stack Trace of High CPU thread from Process Hacker

Edit: Please use stack traces and windbg output with symbols below

In case this is related. I also suffer from Issue 7751, RSS feeds not updating, only one updatng, or only updating once they are added and never again. The icons also remain in the "updating" state.

Here are similar or related issues: https://github.com/qbittorrent/qBittorrent/issues/5097 https://github.com/qbittorrent/qBittorrent/issues/1332

sledgehammer999 commented 6 years ago

That stacktrace is a bit useless without function names. Does process hacker allow to load "debug symbols" or "PDB database/file"? If yes, load qbittorrent.pdb (found in program files) and take another stacktrace.

CeruleanSky commented 6 years ago

@slrslr To differentiate from those two tickets: This started on 4.0.0 , in regards to #5097 all previous versions worked fine.

Inregards to #1332 it isn't frozen or at 0% cpu usage, but listed as using ~100% of the cpu the thread is on.

@sledgehammer999

Just had to add the path to the symbols in the options. Here you go, it does seem it might be RSS and #7751 related.

The problem seems to go away when RSS is disabled.

I hit refresh and while each stack trace was different, it seems that this part is common to them all.

Should be a bit more helpful, here is that 0x2b3 line referenced above:

@glassez this performance issues seem related to RSS. Care to take a look? (see stracktraces above)

@CeruleanSky thanks, those seem helpful now.

CeruleanSky commented 6 years ago

I started experimenting with what feeds cause a failure and tried some external ones I use with other apps. While not containing torrents, this feed worked with the old parser showing all the articles. It seems to run indefinitely with the new parser.

Getting this to work again and show the articles like the old parser did would help with feeds where not every one has a torrent, such as those that mix posts and torrents, or other irregular torrent feeds causing issues, like if a search for torrents is no longer returning torrents.

Do you use an IP filtlist? I was seeing incredibly high CPU and problems starting qbit on Linux until I disabled it with 4.0. Definitely something broken there on Linux...

glassez commented 6 years ago

Working on it...

CeruleanSky commented 6 years ago

@PinaColonic As far as I can tell I am not having any issues with using a IP filterlist and cpu usage. Might want to get a backtrace of the high cpu thread. After it is launched and attached and you ensure you have debug symbols installed, braakpoint In gdb run thread apply all bt. Probably best to open another ticket for that issue or see if one exists.

@glassez Thank you, let me know if there is anything else I can do to help.

Did some testing with disabling RSS. If I disable RSS (untick fetching and auto-downloading in Options/RSS), and then end task in task manager (because it doesn't end by exit), then after restart QBT has normal cpu usage of cca 1-2% cpu.

Then I go to Options/RSS, and enable RSS (fetching and auto DL). Immediately RSS updates, new torrents are added, and CPU jumps to 50-55%, and RSS freezes. Looking at RSS list, frozen icons are on Demonoid rss, all others have regular icons. CPU is locked on cca 55%.

I hit Update All, and all RSS icons freeze (grey circles not moving). CPU stays on 55%. RSS not updating anymore after that.

frozen icons ate on Demonoid rss

Please provide affected feed URL.

MithranArkanere commented 6 years ago

As far as I can tell, the problem only happens with Atom feeds.

After using a tool such as this one: http://feedmix.novaclic.com/atom2rss.php To convert the feed, the problem no longer happened.

glassez commented 6 years ago

The problem is already located, the fix coming soon.

This has another kind of issue. Can someone confirm this feed works correctly in v3.3.x?

Tried the youtube and reddit feeds in qbittorrent 3.3.16

  1. Name of feed and icon updated properly
  2. Items loaded
  3. Content, images, date, author, info looks fine and links work
  4. "Open News Url" right click function takes you to the proper url

PowerfulJre Youtube Channel Feed

Reddit rss

CeruleanSky commented 6 years ago

Can confirm that qBittorrent 4.0.2 win x64 fixes all the issues with the cpu usage I had.
All rss feeds work, at least of mine, loading properly. qBittorrent terminates after closing the window within a very short time.

Thank you.

I'm still having the issue described in #7873 - any advice?
