Hi, My config: - Dell Poweredge R200 - OpenBSD 4.3 - httpd -u - mod_perl (package) - mysql (package) - EPrints (www.eprints.org)
Eprints is leaking some memory. I am in the process of finding the leak.... Anyhow, at random interval the box freezes. I suppose that the memory is to fragmented and the kernel gives up, but I do not know how to debug it. With "vmstat -m | head -n16" I log the "Memory statistics by bucket size". The freeze happens when the 16 is higher than 1,000,000. In httpd.conf, I use "MaxClient 80" and "MaxRequestPerChild 20" to limit the leak. Now I am able to keep the "16" below 800,000. What I may do to help the system to deal with this problem. I would like to relaxe both "MaxClient" and "MaxRequestPerChild". Any help welcome.
