Oggetto: [exim] Deliveries to /dev/null fail
Hi,

I have noticed that my 4.42 servers fail deliveries to /dev/null for some
reason.

The lines from both main log and panic log says:

2004-10-01 11:17:41 queue run: process 4893 crashed with signal 11 while delivering 1CD6Xs-0005bP-8F

Configuration file is /prod/exim/etc/configure

OS is Solaris 8.

bash-2.03# ls -laL /dev/null
crw-rw-rw-   1 root     sys       13,  2 Oct  1 11:18 /dev/null


The rewrite router returns /dev/null, and a debug output gives this at the
end:

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

Considering: /dev/null
unique = /dev/null:nobody@???
post-process /dev/null (0)
/dev/null delivered
doublebounces@???: children all complete

[END OF OUTPUT]


Nothing is actually delivered, log says it crashed with signal 11, and
message stays on queue. And as you can see, the normal debug output for a
delivery doesn't occur.

If I change the alias to go to a file instead, it delivers just fine. I'm
seeing the same problem on other 4.42 installations as well, on another OS
and with other configs. If I replace /dev/null with :blackhole: it works
as it should too.

Any ideas?

Thanks.
