Subject: RE: [Exim] Exim Crashes out with Signal 10
There's a couple of hundred messages total equally 3.5MB in the queue right
now. I've gotten a couple of more errors in the last few hours.

Nothing appears to be amiss. I don't know though. I've got 512MB RAM and 3
GB swap on a PII 350.

Here's where things stand currently (things have not changed much):

Eeew, SIGBUS.

I'd look at the messages in Exim's queue and confirm that none of them
is outrageously large. You might get lucky and find the most files which
Exim touched most recently with ``ls -tu |head''.

However, it wouldn't hurt if you knew what available disk and swap
looked like at the time the error occurred. I'm no expert, but this is
what I'd be looking at.

Good luck!
Sheldon.

PS: If you're running Exim out of inetd, you'll have problems on
    3.2-STABLE. There are a few nasties in inetd which have been fixed
    in 4.0-CURRENT but for which merges are still pending.
