Ah right, thankyou Henrik!

It's odd that it seems to do this most of the time, even when noone
is accessing the cache. Perhaps it is also considering the file
descriptors for the child redirector processes?

 From the squid.conf:

# TAG: shutdown_lifetime time-units
# When SIGTERM or SIGHUP is received, the cache is put into
# "shutdown pending" mode until all active sockets are closed.
# This value is the lifetime to set for all open descriptors
# during shutdown mode. Any active clients after this many
# seconds will receive a 'timeout' message.
#
#Default:
# shutdown_lifetime 30 seconds

Perhaps I'll set this to 5 seconds. ... There are four squids in
accelerator mode behind a load balancer. We want to be able to take
one out of service with minimal impact on user experience. Currently
you randomly get a "squid is shutting down" error if you do this.
Closer interaction with the Cisco CSM load balancer could also be a
better way to do this!

Cheers

Jesse
