----------------------+-------------------
 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:

 {{{
