[squid-users] Resource temporarily unavailable

I found squid today terminated abnormally

I have been using squid for months with no problems its been acting up
lately
I found it today

There is a cache log snippet at the end of the mail which repeats itself
every 30 seconds

storeDiskdSend OPEN: (35) Resource temporarily unavailable
2004/05/07 12:32:53| storeDiskdSend: msgsnd: (35) Resource temporarily
unavailable

This is really strange as no body is generally using it at this time. Its
my personal
gateway and I was snuggly asleep at 1 am last night.

Any ideas?
