nessus crashes AIX

Subject: nessus crashes AIX
Date: Mon, 28 Feb 2005 16:06:21 +0000
Hi,

When I've tested our AIX 5.1 server with nessus 2.2, it started to slow down
(maximum processor usage, and IO usage) and twenty minutes later it stopped
responding. After the reboot, we found out that the system crashed because of
the swap space was full, so this is like a memory leak or an unwanted DoS attack
triggered by Nessus.

We investigated the problem, and found out that the only tests that can cause
the crash is:

rpc_portmap.nasl, or
find_service.nes

The interesting thing here is that we already scanned a lot of other AIX 5.1
servers without errors (using nessus 2.0, and also 2.2). This is the only
system which we have troubles with.

Has anyone experienced such problems with AIX before? Is there any way to find
out what the problem was (we don't want to crash the server anymore)? 

Any help would be appriciated.
