MailScanner eats memory out

[Arthur Sherman]

Hi,

This started recently, probably after I have installed RDJ.

The server has 1GB of memory and was happily utilizing ~300 of it.
Now it eats up everything.
When I rebooted the server and checked 'top' there hardly was 30MB free,
which then climbed to ~120MB.

'ps' shows this:

Which clearly shows that MS is responcible for this.
Please mention that this was in quitest time - actually no mails at that
time in maillog.

Does anyone has a clue what to do in this case?

Thanks.


Best,
