What external event(s) happen at that time? Something is probably
sending a signal to the logging daemon process. It would be good to know
what that something (and that signal) is. Your syslog or cache.log might
contain more info. Analyzing the timing/schedule of these problems may
also be helpful in identifying the trigger.
Is a possible workaround that might be just replacing the line with
this?
> access_log /var/log/squid/access2.log
As you know, this configuration (in this deprecated spelling or with and
explicit "stdio:" prefix) will result in Squid workers writing to the
log file directly instead of asking the logging daemon. This will,
naturally, get rid of the pipe between workers and their daemons, and
the associated broken pipe error.
or will this cause a problem?
Impossible to say for sure without knowing whether your workers benefit
from the anticipated performance advantages of avoiding blocking file
I/O _and_ whether those advantages are real (in your environment). Too
many variables and too many unknowns. I would treat this as an important
(and potentially disruptive) configuration change and carefully test the
outcome.
HTH,
Alex.
