It sounds mostly like a resource issue, but I can't say exactly from
what you have provided.

You can consider increasing the "cli_timeout" parameter a bit
and see if it is simply a matter of a busy machine.

Are you running on 32 bit or 64 bit machines ?

If 32bit, you have to be pretty careful about not overrunning the
VM space available (only approx 2G)

Use FreeBSD's gstat to see what your disk-activity is like,
pay particular attention to the service times (ms/r & ms/w cols)

Also check your varnishlog and varnishstat for signs of trouble...

Never attribute to malice what can adequately be explained by incompetence.
