Periodic Buffer overflow - Query_volume_information
Posted: Tue Nov 07, 2017 10:57 pm
Hello!
I've probably messed up a Libtorrent-setting(ItConfig) to cause this or at least amplify it, but cannot for the life of me figure out what.
Every 6 minutes (Cache expiry time) when the throughput is high(70-100MiB/s), speed drops to zero for half a minute then recovers. Ran Process Monitor to see what goes on when that happens, and during that time it seemingly reads/checks every file of every torrent that is added(≈100, around 6TB) even if the torrent is paused. This is OK for the SSD's, but my poor rust-drive RAID10(T:) takes a little while to serve these requests.
Why is it happening, and what can I do to mitigate or fix this?
Deluge 1.3.15 - 1.0.11.0
Windows 7 64bit
Thanks for your time.
edit: Solved after restart of daemon. Suspect it'll start up again if I resume torrents that are on the RAID. A very similar thing happens if there is any significant throughput(a few MiB/s) on any torrent on the RAID. Disk IO for the RAID gets overloaded for 10+ seconds, then recovers for a short while and repeats. Haven't had a chance to take a closer look at what actually goes on when that happens, but will test further tomorrow.
Any suggestions on what causes this so I can avoid it in the future? Plenty of free system resource(s).
edit2: Problem back without changing a thing. Some time during the night, the periodic check-every-file started back up.
