rTorrent Crashing

hotes · September 1, 2016, 11:20pm

Just had a few questions regarding getting my server working. I have reinstalled twice now, and I am having the same issue. Once I get everything up and running and try to use blackhole to start some torrents, everything starts fine, then a few seconds later the physical memory starts to climb, when it maxes out rtorrent crashing and then I get into a loop of restarting, maxing ram and crashing.

In addition, I thought I have fixed the diskspace problem. After trying to completely reboot system, once its boots back up the problem is back and my previous solution no longer works.

Thanks for any help.

A couple of things to point out to hopefully add a bit of clarity.

Physical Memory Usage is nothing more than Memory at work. This implies that your RAM is doing it’s job and this is not by any means the actual amount of Used RAM on a system. Take note of your Real Memory Usage as this is an indicator of your actual RAM in use. Physical Ram hitting between 95% - 98% is common and expected behavior. This is a part of your systems RAM that is always there, QuickBox just exposes it to you for transparency.

Hard to say without knowing what your previous problem was and as well as your attempted fix at some scenario. If you could provide more details with what the problem may had been, we can issue a concrete solution for you… no need for guess work on your end, it’s what we’re here for

To focus on you first issue:

When it crashes, if you do systemctl status [email protected] and we’ll have something to go on. Without any real evidence of the issue, it’s fairly hard to troubleshoot… the status will at the very least give us a small clue. Additionally, any other information such as the OS you are on will be helpful.

Thank you for your quick reply.

I figured as much for the first issue, was just trying to best describe the crashing process.
Cold rebooting causes the used portion to go negative, (-1468ish GB), I used setdisk again to 1800GB and it updated on Webui

Are you on Debian by chance?

Also, if you could do a quick cat /etc/fstab

Are you replacing the USERNAME with your actual username in this command?

Well that’s embarrassing… but here is the result

I run systemctl restart [email protected], then rerun status, I get active (running) then abou 15 seconds into “checking” active torrents it crashes again…[01.09.2016 20:02:59] Bad response from server: (500 [error,list]) Link to XMLRPC failed. May be, rTorrent is down?

JMSolo · September 2, 2016, 12:03am

This type of behavior actually sounds like you have a bad torrent that is corrupting your session.

Try rechecking them one by one until you hit the sweet spot. The bad one (once it attempts to recheck) will immediately crash rtorrent.

hotes · September 2, 2016, 12:15am

Thank you, that seems to have worked. Never thought that would be a problem, a few years on my old seedbox, never had a bad torrent.

One more question if you have a second. Ever since I rebooted I cannot get my other services to restart, clicking refresh does nothing. Also attempted to uninstall, reinstall.

Can you give me the output of uname -a

JMSolo · September 2, 2016, 12:28am

If you do systemctl restart [email protected], does the service enable and stay active?

hotes · September 2, 2016, 12:30am

Job for [email protected] failed because the control process exited with error code. See “systemctl status [email protected]” and “journalctl -xe” for details

also, rtorrent crashed again, I think it might be an issue of diskspace. I have plenty of space but the details on the torrent state Low diskspace

JMSolo · September 2, 2016, 12:39am

I am thinking it may have to do with blackhole. I don’t personally use a blackhole folder so I can’t confirm this.

Hmm, this is suggesting then that it simply will not start. What does journalctl -xe show. @liara may also have some additional feedback on this once she is around.

Ah, this may be your issue.

Will you do this as root user fix-disk_widget_root and see if that settles your Disk Status Widget on the dashboard. Additionally, are you using the diskspace plugin… or does it say that diskspaceh

Since you are using journaled quotas… there should be no issue, so I am thinking it is reading from the wrong mount for some reason. With that said… so you need Quotas installed?

hotes · September 2, 2016, 12:40am

I edited my previous post, Im thinking its something with available space (I know nothing about linux HD allocations)

I originally didn’t install quota. But to fix my widget I already entered that, installed quota then used setdisk to fix the widget.

diskspace is uninstalled, current have diskspaceh active

JMSolo · September 2, 2016, 12:48am

uninstall the diskspaceh and install diskspace and that will sort your rtorrent issue in that regard.

Removing the quotas package will fix your Disk Status Widget as long as you have it calling the right mount, which that command will address. I know we have a considerable amount of Kimsufi users, this is just one such situation that has never cropped up.

hotes · September 2, 2016, 12:52am

Ok we are getting somewher, I uninstalled spaceH, installed diskspace, removed quotas.

Now widget says 0GB free, 19GB used
Rutorrent is finally showing disk usage in bottom left, and giving me the full disk warning.
