Hey guys, Our requests seem to be getting timed out. I set all the timeout parameters pretty high, so wondering what could be causing it.
Also, how do I check out the number of current threads being used in varnishstat? Thanks, Tung # ps auxww | grep varnish root 2649 0.0 2.4 101776 82744 pts/0 S< 13:48 0:00 varnishlog -w varnish.log root 4301 0.0 0.0 110552 1136 ?
