Hello People,
I've just setup a squid proxy at a local school. It's been humming along
fine for two weeks now. Today it started to work rather sporadically.
I'm using squid-2.5.STABLE10-transparent from ports, on an OpenBSD
snapshot from 1st september (too be upgraded to -stable on Nov 1st).
/var/squid/logs/cache.log tells me this:
2005/10/14 08:56:55| storeDiskdSend OPEN: (35) Resource temporarily
unavailable
2005/10/14 08:56:55| storeDiskdSend: msgsnd: (35) Resource temporarily
unavailable
So for some reason diskd is choking. Through google I found this thread,
discussing the same symptoms:
http://squid.bilkent.edu.tr/mail-archive/squid-users/200212/0354.html
As told there, it's problably IPC settings that should be adjusted. The
squid FAQ tells me to fiddle in the kernel config:
http://www.squid-cache.org/Doc/FAQ/FAQ-22.html#ss22.6
But since GENERIC is holy for me, I'd rather not poke around and have to
run a custom kernel. Is there any other way to change these values?
With config -e /bsd I found that SHMSEG and SHMMAXPGS could be changed,
but I'm not sure these are the ones I should touch? In sysctl there
seems to be a bunch of values in kern.seminfo. But again, those are not
named like the values in the squid FAQ.
Any tips/pointers on how to make squid a more happy fish?
