[squid-users] storeDiskdSend OPEN: (35) Resource temporarily unavailable

Hi all,

I'm running squid 2.6-stable17 on Freebsd 6.3. Machine is a 500MHz
with 512MB RAM.

./configure --prefix=/usr/local/squid --enable-
storeio=ufs,coss,diskd,null --enable-underscores --with-large-files --
enable-large-cache-files --enable-delay-pools --disable-ident-lookups
--enable-snmp --enable-cache-digests --enable-underscores --enable-
kill-parent-hack --enable-removal-policies --enable-async-io --
enable-kqueue --enable-follow-x-forwarded-for

I just have squid displaying the following error message:

2008/01/20 18:24:15| storeDiskdSend OPEN: (35) Resource temporarily

There's only 4 users on this server, and it's been running for quite
sometime now.

I read that I need to increase the message queue limits, Im presuming
it's the "kern.ipc.msgmnb=16384". How can I monitor system before
anything happens. I can run squidclient mgr:info, but what do I need
to look for.

Configured thee system with following parameters:

kern.ipc.nmbclusters: 65536
kern.maxfiles=65536
kern.maxfilesperproc=32768
net.inet.ip.portrange.last=65535
kern.ipc.somaxconn=2048
kern.maxvnodes=100000
kern.ipc.msgmnb=16384
kern.ipc.msgmni=40
kern.ipc.msgseg=512
kern.ipc.msgssz=64
kern.ipc.msgtql=2048

options SHMSEG=16

options SHMALL=4096
options MAXFILES=8192
options NMBCLUSTERS=32768
options MSGMNB=16384

In my squid.conf:
cache_dir diskd /usr/local/squid/var/cache 28000 32 512 Q1=72 Q2=64
