All,

I am seeing the following error showing up in my logs every 5-10 minutes.

==> /var/amavis/amavis.log <==
Feb 4 15:20:09 domain.net qmail-queue[25449]: starting. qmail-queue 0.3.12 Thu Sep 11 11:52:40 EDT 2003
Feb 4 15:20:14 domain.net qmail-queue[25449]: do_exit:410 - ending execution with 81

Error "81" is identified as being a "internal bug, eg. segfault".

Does anyone know what could be causing this?

Earlier today I was getting the following error:

==> /var/amavis/amavis.log <==
Feb 4 14:37:14 domain.net qmail-queue[7925]: decoding failed, retry: Possible DoS detected - mail requeued at bin/qmail-queue line 905. (message-id=)
Feb 4 14:37:14 domain.net qmail-queue[7925]: do_exit:437 - ending execution with 81

Which I fixed by modifying /var/qmail/bin/qmail-queue:

Maximum nesting level for compressing archive formats
>> 905 # default: 3. If set to 0, feature is disabled
$MAX_ARCHIVE_NESTING = 0;

- Changed from 3 to 0.

Does anyone know what would cause this problem or how I can fix it?

Thanks.
