On my NetBSD 1.5.x box, it's even worse - syslog-ng 1.5.13 dumps core
when it gets HUP'd, due to this assertion:

   assertion "s->ref" failed: file "center.c", line 129

The core file helpfully has a message on the stack saying it couldn't
open /dev/klog, device busy, and I confirmed with ktrace that syslog-ng
is closing its other sources in my config file, but not the
file("/dev/klog") source.

When I take the file("/dev/klog") source out of the config, it doesn't
crash anymore.  A bug in the class for file() ?

Balazs, let me know if you need any more diagnostics.
