The idea that comes to mind (for me) is that it may be a queue delay in
the UDS kernel I/O subsystem if your Squid is processing much traffic
shared between workers. The SMP coordinator process that arbitrates all
that plus generates these reports may be heavily loaded with work.

If it is a bug, whoever looks into it will likely need a ALL,9 cache.log
trace to have a chance figuring out what the problem might be.
