i have strange not easily reproducible stalls.
on a debian squeeze varnish 3.0.2-1~1squeeze1 runs in front of very slow
php scripts on apache 2.2.16-6+squeeze3. the machine is a virtual
machine with 4gb of ram and 2 cpus.
the vcl w/o comments is below, the varnishlog with maybe too much output
is at . the vcl is at .
i hope, i did not forget necessary information.
the problem is the following. sometimes (in this example at about 20:43)
it stalls for about one to three minutes. there are some timeouts in
that timeframe, but i fail to see the reason. without varnish in front,
apache does not show such stalls (but because it has been so extremly
slow, noone really knows). i found one bug (#951, ), that described
similar problems, but here, we explicitly return (pass) these urls. so
the workaround mentioned there (req.hash_ignore_busy=true) as expected
does not work.
if you have any pointer on how to proceed, i'd be glad to know.
