still trying to purge

[Charlie Farinella]

As long as I'm being a pain in the neck and asking a lot of questions, I 
have another:

Sometimes ( not always ), purging the cache crashes Varnish.  I have it 
monitored by monit which restarts it, but it would be better if I could 
prevent that.  Is this a known issue?  Misconfiguration?  

Version 1.1.2 installed via rpm on a RedHat Enterprise 5.1 server.
