varnish suddenly restarting / flushing itself after several hours?

[Frank van Lingen]

Below the last messages. These are two restarts within the hour, but
most of the times it seems to run for several hours 4-8 without
problems.  I could not find any panic messages. I found some messages
in the varnish mailing list regarding this but the only ones I found
where 'died signal=6'
