Title: Problems with clamav and "malformed database"
Post by: purpaboo on April 01, 2008, 01:53:45 PM: Hi

I've had issues with sending mail over the last 18 hours or so, and managed to track the problem down to clamav (I think).

The problem seems to be a corrupt clamav database.

I'd log this in the bug tracker, but while my email is down I can't create a login.

Here's what I get when I try to restart clamav. Any tips appreciated:

Code: [Select]
[root@www ~]# /etc/init.d/clamd restart Stopping Clam AntiVirus Daemon: [ OK ] Starting Clam AntiVirus Daemon: clamd daemon 0.91.2 (OS: linux-gnu, ARCH: i386, CPU: i386) Running as user clamav (UID 407, GID 402) Log file size limited to 1048576 bytes. Reading databases from /var/clamav Not loading PUA signatures. LibClamAV Error: Empty database file LibClamAV Error: Can't load /var/clamav/daily.inc/daily.zmd: Malformed database ERROR: Malformed database

Thanks

Pete

What process calls clamd?

Thanks

Pete

In SME server, clamd is a supervised service. You can stop it via:

sv d /service/clamd

and start it via:

sv u /service/clamd.

Do not use /etc/rc.d/init.d/clamd.

I'd suggest you read the Developers Guide to learn more about SME server internals.

I've had a look through the developer's guide and can't find any reference to using "sv u" or "sv d" and very little reference to clamav at all.
