Morning ...
Running -STABLE from Fri Oct 26 19:02:17 CDT 2001, I've been
getting a panic almost every morning, at ~2am, with the following:
panic: pmap_new_proc: u_map allocation failed mp_lock = 00000001; cpuid = 0;
lapic.id = 00000000 boot() called on cpu#0
Does anyone know of any issues around that date that has since
been fixed? I'm currently recompiling/upgrading my kernel to todays
-STABLE, in the hopes that this will help fix it ...
I have maxusers set at 1024, and maxproc is working out to be:
jupiter# sysctl -a | grep maxproc
kern.maxproc: 16404
kern.maxprocperuid: 16403
According to a script I'm running once a minute, around 2am, the
number of processes on the machine increases to just over 3700 before it
crashes:
