Has the meaning of maxfiles been changed somewhere ?
Before the great VM/buffer merge (which works great down here with
today's patch fo vfs_bio), my system-wide max # of open files was
about 680 or 700 (pstat -T).
Now it seems that the max # of open files PER process has become
thet system-wide limit...
223/256 files
677 vnodes
17M/64M swap space
and 256 files are very easy to have system-wide opened...
Jan 11 23:10:42 keltia /kernel: file: table is full
config file follows, I added
options "CHILD_MAX=128"
options "OPEN_MAX=128"
When I ran out of processes... a while ago (duriing my 1.1.5 to 2.1
change).
Is there something I've overlooked ? Before the VM change it was
running without that problem... maxfiles is hard-wired as 256
in param.c which is very reasonnable of a per-process limit but
not as a system-wide limit.
David, John ?
