I upgraded the servers to Varnish 3.0 (with same configuration) and
stopped getting Connection Reset errors. The memory consumption is
still high, but not as high to give me errors. It's working fine now
with high traffic for days along =)

memory maps per proccess is a lot less to. 100k+ to 12k stable.

The only strange thing is sometimes I'm still getting many stats on
'n_wrk_max - N worker threads limited', but it seems that the worker
queue is working just fine.

Thanks =)
