Hello,
I've been having this issue for about a year, but haven't had the time
to fully diagnose this, and the servers that had this problem didn't
have a need for 4GB of ram, they just happened to have 4GB, so the
solution was either to remove 2GB, or set hw.physmem="2048M" in
/boot/loader.conf. I finally have enough free time to try and diagnose
this, but I'm not finding it easy to figure out what's going wrong.
I have about 10 servers like this, Dell PE2650, 6GB of pysical ram
using Dell's "Redundant Memory" feature which leaves the system with
4GB of "usable memory", AAC Perc3 card with RAID5 volumes. All of them
running apache 1.3, and the ram is mostly used for filesystem cache.
It looks to me like the bug exists somewhere in the filesystem cache,
and unfortunately that's very heavily used here.
With 2GB of ram, the servers run for months without problems, with 4GB
of ram, they crash within 2 minutes of taking a real load.
This isn't a "bad hardware" issue, as it happens the same across 10
servers, and the problem is resolved without changing any hardware,
only changing /boot/loader.conf to limit the ram to 2GB.
Has anyone seen this before? Any ideas on what might be wrong?
