[galaxy-dev] Job runner out of memory problem

It seems that even under very light i.e. just a couple of long-running jobs present load the job runner slowly, but steadily (1-3Mb per sec) grows its memory consumption until it's killed by linux OOM killer. My job runner config: http://pastebin.com/vMWDHAQm I'm currently restarting the runner out of crontab when it is killed by OOM, but it's not a sensible solution by any means. I wonder if anyone encountered this and how it was solved. Thanks, Alex
