Cannot allocate memory

[meokey]

I'm running sabnzbd on Drobo FS which is a small NAS with small embedded memory which means I have no way to add. Now I have such an error message

Code: Select all

2012-03-29 11:00:31,603 ERROR: Error [Errno 12] Cannot allocate memory while running par2_repair on set NCIS.S09E17.720p.WEB-DL.DD5.1.H.264

Does sabnzbd have an option to limit the memory usage, or can someone suggest a set of parameters fitting embedded systems? Thank you very much.

How much memory do you have?

FWIW: I run SABnzbd on a headless system with 256 MB RAM like this:

Code: Select all

Mem:    243268k total,   239076k used,     4192k free,    31824k buffers
Swap:   524284k total,    57972k used,   466312k free,   106484k cached

In the meantime, check out http://forums.sabnzbd.org/viewtopic.php?t=4886 about memory usage and ... nzbget.

EDIT:

PS: as a test, I turned off swap, and that works too (tested with a 1 GB download)

Code: Select all

Mem:    243268k total,   215020k used,    28248k free,    22916k buffers
Swap:        0k total,        0k used,        0k free,    36076k cached

I followed the tips by shypike, it does look better but still consuming a lot of mem.

Code: Select all

  PID  PPID USER     STAT   VSZ %MEM CPU %CPU COMMAND

Wondering whether sabnzbd will have a special configuration for embedded systems in future releases ... comparing NZBGet that "seems to use up about 15MB of memory per connection, so about 60MB with 4 connections"
