I run a FreeBSD 2.2.2-R box as a printer server for a couple of days. The
system worked fine before with 2.1.6-R for more than a year.
There are a lot of printer queues (about 70) and a lot of complex(?) input
filter scripts. Sometimes the system is heavily loaded.
Occasionally some queues stop working with an error message like `fork:
resource temporarily unavailible'. So
(i) I recompiled the kernel with MAXUSERS=20 to be sure,
(ii) I removed all limits on # of processes in /etc/login.conf
(and ran cap_mkdb /etc/login.conf),
(iii) but nevertheless the (bash) filter scripts still had a soft limit
of 40 processes which seems to be to low.
So where does this limit come from? I've no idea.
As a workaround I modified /etc/rc in this way:
(
ulimit -Hu 300 ; ulimit -Su 300;
echo -n ' printer'; lpd
)
Now the filter scripts run with a soft limit of 300 processes which seems
to help.
Has anybody a better idea? Or do I misunderstand something?
Thanks
