RE: Router dies off

[Amir Sedighi <amir@rogerswave.ca>]

HELLO:

Oh I had an even worst case with 2.99.49p9.  If a message had MAIL FROM:<"<>"@domain.com>, the router would start eating up all the memory on the box until the box became a useless zombie which needed physical rebooting.  Has this particular problem been fixed in the newer versions?
My OS is Solaris 2.5.1 and is patched up.

Thanks,
Amir.

router used to have quite a few problems that caused segfault on various
"abnormal" messages (i.e. with syntax error in the headers).  You
may want to upgrade to the most recent snapshot, and it the problem
persists, look for a 'core' file in the $POSTOFFICE/router directory
and try to analyze it...  I think that in your version the router
used to rename the 'core' file and move it into .../postman directory.
