varnishncsa outage

[Jean-Baptiste Quenot]

Hello list,

We are running varnish 3.0.1 rc1 in production since a few days, and
notice that varnishncsa sometimes disappears!  It runs for hours and
suddenly exits without an explanation.  The only exit() calls I can
find in the code are when the format string is invalid, which would
only occur on start.

No core dump, no kernel message.  I don't know if varnishncsa printed
an error because when run as a daemon there is no error log (maybe
using syslog for this would be more appropriate BTW).

Your help will be appreciated,
