I installed transmission2.03-1 from Kylek's repo. Installed fine. Fired up transmission and a few torrents.

However I notice three problems:

1. High cpu usage. running top command shows upto 80% cpu usage. Please see attached screen shot file for more info.

2. I notice multiple instances of the transmission-daemon showing up in the list of running processes? Is this normal? Can someone confirm?

3. Transmission sometimes stops by itself. I have then ssh into the NAS and then start transmission again.

Anyone have any suggestions or fixes?

Thanks!

THe only one I can answer is #2. It is normal to have more than one process/thread for transmission. I haven't seen the other issues you mention.

1) Is there any activity in the transmission? Such usage may appear while rehashing or hi-speed downloading|uploading.
2) normal
3) what you see in logs? If nothing then try to run transmission in screen. (search KyleK's transmission thread for howto)

Thanks for your replies!

1. I see the point. If transmission crashes, then the rehashing has to happen, which can consume cpu cycles. I think this could be the case, because I checked the process using the top command after 30 minutes after power up, I saw only 5 transmission processes and cpu was more like 25%.

2. Good to know its normal.

3. I will read through the big thread. If you could post the relevant post that you want me to read, it would be very helpful.

Thanks again.

Something like that:

1. Install this.
2. Open a new screen by simply typing "screen".
3. Make sure Transmission is shutdown (/ffp/start/transmission.sh stop, wait a little while)
4. Start Transmission in foreground:
Code:
$ transmission-daemon -f -g /mnt/HD_a2/.transmission-daemon
5. You should see normal Transmission output right in the console. You can also check if it works correctly by accessing the web interface.

Installed screen and have been running transmission. Transmission crashed once, but I could not open the log. It complained about not being able to open the log.

root@nas:~# cat /mnt/HD_a2/.transmission-daemon/transmission-daemon.log
[21:38:29.301] Couldn't read "/mnt/HD_a2/.transmission-daemon/settings.json": Permission denied
[21:38:29.302] transmission-daemon Error loading config file -- exiting. (daemon.c:421)

Also I now notice that I can't open transmission normally

root@rnvnas:~# sh /ffp/start/transmission.sh start

does not start the transmission process. But running through kylek's screen option does. and I can see the output on the screen.

Bump!!! Anyone have suggestion?

1. I can't open the transmission log.

2. Now I notice that I can run transmission on screen, but transmission will not run otherwise.

Help appreciated!

Code:

chmod -R 0777 /mnt/HD_a2/.transmission-daemon

Try this and then run transmission again.

vishnumrao · 2010-08-22 08:44:11

I tired the suggestion. I was able to read the logs but noticed nothing unusual. It had the same contents as what was being printed out when transmission was run using the command

transmission-daemon -f -g /mnt/HD_a2/.transmission-daemon

I have been experimenting a little bit. I notice that if I run 3 torrents or less, transmission is stable. It has not crashed in the last 5 hours. But if I have 4 or more transmission crashes. Even if I have total of 10 torrents, with only 3 running, transmission crashes. but if I remove 7 paused torrents no problem. Any clue why it could be happening?

Very strange. I've had 20 or so running without a problem.

Maybe clean install from the scratch will help.
