Description Daryll 2008-11-27 03:05:33 UTC

Description of problem: It appears that Tranmission stores a copy of the content that you are downloading in RAM. Therefore if the content you want is multiple gigabytes (such as the Fedora release DVDs) transmission will likely run your system out of RAM. I currently have three torrents downloading and transmission is using 770MB. The total content downloaded at this stage is about 700MB. The RAM usage seems to grow very consistently with the pace of the downloads. 

Once one of my downloads finished I removed it from transmission and then restarted the application. The RAM usage dropped to 53MB, and then continued to grow as transmission downloaded files.

v1.40 is now available upstream.

Version-Release number of selected component (if applicable):
transmission-1.34-1.fc10.i386


How reproducible:
Every time

Steps to Reproduce:
1. Start a torrent of a well seeded large file
2. Watch VIRT column in top
3.
  
Actual results:
Memory grows as file downloads

Expected results:
Memory remains constant

Comment 1 Denis Leroy 2008-11-27 09:58:37 UTC

Hmm, can't reproduce with 1.40.

Comment 2 Daryll 2008-11-27 16:13:04 UTC

Right. I'm still running 1.34 which is in F10. I thought maybe 1.40 might fix it if the maintainer released it.

Comment 3 Denis Leroy 2008-11-27 17:00:51 UTC

1.40 will be pushed to the updates-testing repo shortly.

Comment 4 Charles Kerr 2008-11-28 22:49:28 UTC

Neither 1.34 nor 1.40 hold the copy of the torrent in memory.

I can't reproduce this error, either.
