Varnish hangs .

[Paras Fadte]

Hi,

I have encountered a strange problem with varnish wherein it just
hangs and stops responding to http requests even though it is in
running state . The backends run without issue , one can telnet to
varnish console also . What could be the issue ? I had downloaded
varnish from trunk also to check if this issue goes but it tends to
reoccur .   I get following messages in varnishlog .
