Hi,
I'm running a debian sarge server with a few Zope-instances. A known issue with Zope is, that it is very RAM demanding. Anyways, what I want to do is to limit the physical memory my Zope processes can use. Some people are doing this with DJB's daemontools. If possible, I'd like *not* to use daemontools. I thought ulimit could do the same thing for me - seems that I was wrong or I'm doing something wrong.
I tried to set a memory limit in /etc/security/limit.conf: zope hard rss 65536
I tried to set a memory limit in /etc/profile: ulimit -m 65536
I tried to set ulimit in the Zope startup script: #!/bin/sh ulimit -m 65536 exec "/path/to/runzope"
All the above setups should, at least to my understanding, set a limit of 64 MB. I didn't get any positive results when running a test below.
Test: * start zope * watch memory usage with top * make zope use much memory, i.e. up-/download a large file * watch the process bypass the memory limit with top
What am I doing wrong. It's probably obvious, but I'm somehow stuck.
Thanks, Michael
