     Type:  defect    |     Status:  new
 Priority:  normal    |  Milestone:
Component:  varnishd  |    Version:  3.0.3
 Severity:  blocker   |   Keywords:
 I am running Varnish 3.0.3 in FreeBSD 8.3 with the following vmods:
 header, curl, var, authentication, digest, paywall (custom - developed by
 Varnish Software) and softpurge.

 After running for some days and doing softpurge every so often, Varnish
 instantly crashes with the following logged to syslog:
