Hi!
I have a little problem with transmission 2.22 (and other versions). It's crashes:

May be we can minimize memory usage? Or use swap file?

KyleK · 2011-04-20 19:04:28

Hm, that is strange. I've seen Transmission use 45% of system memory yet it never has crashed for me for that reason. Your dmesg shows tha swap is plenty available.

Are you sure Transmission is the cause for this?

Elmor · 2011-04-21 13:03:43

Can you attach your Transmission's settings.json (don't forget to remove any auth info ?
Also, what usage are we talking about (how many torrents loaded/downloading/seeding)?

Elmor · 2011-04-21 22:11:23

about 15 stopped torrents
1-2 checking
1-2 downloading

Attachments:

ckarv · 2011-04-26 13:22:26

What would you say is the maximum recommended amount of torrents (active/seeding) in Transmission on a DNS-320?

I'm using both the webgui and the "Transmission Remote GUI", and they are becoming more and more unresponsive as my torrent count has increased, and is now around 80.

Thanks

Edit: Rebooting (41 days since the last reboot) actually helped significantly, now Transmission is very responsive again. Memory leak, or what could cause this?

Hi all.
I've just tried to download the client, but the kylek.is-a-geek server appears to be down. Is that temporary or should I try to look elsewhere to get the client for my dns-323 ?

Thanks

KyleK · 2011-05-06 13:57:45

It's only temporary, the DynDNS host seems not up-to-date. Just wait a while, it should work again soon (in ~4 hours at the latest, when I'm able to do the reset manually).

Trenien · 2011-05-06 14:00:48

Ok, will do.
Thanks

FunFiler · 2011-05-06 19:44:37

If you don't want to wait, I've posted links to an alternative site earlier in the thread.

What is the optimal settings of the settins.json file? I did not change anything in the connections part.
Is it a solution if I would use a pendrive to extend the swap file?
It is a DNS-323.

Elmor, Cirip,

If transmission crashes repeatedly, especially soon after start up, it will be because of it choking on one of the incomplete torrents its trying to verify. If you're quick you may be able to remove the torrent with the webUI before transmission crashes, otherwise remove the relevant torrent in the configdir/torrents (and perhaps the partial download in the incomplete directory) when transmission isn't running and restart.

ABCC · 2011-05-14 11:36:57

After upgrading from 2.04 to 2.22 it seems the script I've written to run upon torrent completion is no longer executed. According to the changelog of 2.20: "Improve support for running scripts when a torrent finishes downloading", so perhaps something was broken. Has anyone else encountered this and/or have a working torrent-done script in v2.22?

FunFiler · 2011-05-14 14:20:19

I have been running a script on torrent completion for some time. I had no issues when I upgraded to v2.22. Sorry, it seems to work fine for me.

ABCC · 2011-05-15 12:44:09

Cheers for confirming that it ought to work. I went back to my old test script and confirmed it didn't work even though the log showed it was being called. After a downgrade to 2.11 and seeing it working I did some stubble scratching then wandered off to make some coffee. No sooner had I reached the kitchen that it dawned on me. Ran back, added a shebang to the top of my test script, upgraded, downloaded the same ebook for the 10th time et voila, my test script actually did what it was supposed to.

So, as of 2.20ish you've got to have a shebang for your script to run.

Thanks again.

FunFiler · 2011-05-15 18:39:50

Good to hear you got it working. I'm surprised it worked without the shebang to begin with.

Thanks ABCC the answer!

But I think the program doesn't crash just not enough memory.

dmesg says:

..
Out of Memory: Killed process 1693 (transmission-da).
Out of Memory: Killed process 1707 (transmission-da).
..

All torrents I am downloading is working. No problem with verifying.

Are you any other hint?

Best Regards:

C.

ABCC · 2011-05-15 22:27:27

Hi Cirip,

You're right in saying it's not a crash but an out of memory error. The operating system has killed transmission to ensure that both it and all the other applications can keep running. Usually this is caused by a memory leak in the app that was killed, on an overloaded server however it's possible that the app that consumes the most memory rather than the one that's causing the problem is the one to be killed.

The only time I've had transmission exit due to the OOM-Killer is due to there being 'something' wrong with a particular torrent. Normally it takes a while for me to notice it. Keeping an eye on the verifying process after a restart usually shows up which torrent causes the problem, deleting it provides the solution.

Perhaps a better method for finding out which torrent is the problem is to simply pause them all and then finish them one by one. If one really is bad it'll crash transmission quite consistently so it's quite noticeable.

As for other ideas, occasionally transmission gets stuck when i download a very well seeded file or many files at the same time. Eventhough I use bandwith limits to ensure transmission doesnt use up all of my bandwith the download rate can make transmission completely unresponsive or even crash.

Unless you're simply overloading your NAS with transfers my suspicion is that one of your torrents has somehow gone wrong. As such it's now ruining it for all the torrents by having transmission-daemon wiped out by the OOM-killer*. Deleting it and requeueing it will prove to be the solution, which one it is however is up for you to find out. Pause them all, restart half and let them finish. Repeat til it crashes, pause them all then restart half of the ones that were running. Repeat til you find the broken torrent.

Or maybe it's time to pull the drives out and run fsck on them....?

HTH,

ABCC

It's time for a new Transmission release. v2.30 is up and running.
As always, check the first post for the download link and Changelog.

I made some minor changes to the start script. Please let me know if you run into problems starting/stopping Transmission.

Also, of course, I'd like to know how the new version is working out for you

Cheers!

I have a problem to stop trans:

Code:

# ffp/start/transmission.sh stop
Stopping transmission-daemon
[22:15:22.865] transmission-remote: (http://localhost:9091/transmission/rpc/) Timeout was reached

And when transmission is run - cpu load is 0%.
WEB GUI don't reacheble. But "top" command is show that transmission is run

Code:

# /ffp/start/transmission.sh stop
Stopping transmission-daemon
Unexpected response: <h1>401: Unauthorized</h1>Unauthorized User

Ufffffff O_o

I can stop trans only via

Code:

killall -9 transmission-daemon

Hi Kylek, I have the following error message when I try to stop Transmission 2.30 on DNS 323:
Unexpected response: <h1>401: Unauthorised</h1>Unauthorised User

FunFiler · 2011-05-17 23:32:16

No issues here, but I used my saved scripts to stop/start as I've adjusted them a bit to suit my needs.

Bah! You're right, I didn't consider people with active authentication.
To explain: Since a few versions ago, you can use 'transmission-remote --exit' to tell the daemon to quit, which I think is much nicer and cleaner than send a 'kill' signal.
Of course, if you activate authentication, the above command needs to be changed accordingly.

I've updated the package in the first post with a new start script that reverts to the old "stop" command.

KyleK · 2011-05-18 16:20:34

The Transmission crew released v2.31 today, but I won't make a package of it.
The difference between v2.30 and v2.31 is miniscule and I incorporated the cange into my build of v2.30.

In short: My Transmission package of Transmission 2.30 is virtually identical to v2.31.
