 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 .
 {{{

     0 ExpKill      - 958922603 -30

 Thanks in advance.
