MailScanner - OpenSUSE 10.1 - ClamAV trouble

[Dirk Enrique Seiffert]

Hello I use MailScanner on various Opensuse 10.1 Mailserver. About two
days ago I updated the ClamAV Opensuse rpm to clamav-0.90.3-3.1 - Since
then it takes an eternity to scan for virus.

Jul 12 18:56:57 mail MailScanner[25523]: Virus Processing completed at
195581 bytes per second
Jul 12 18:56:57 mail MailScanner[25523]: Batch completed at 19 bytes per
second (2320 / 117)
Jul 12 18:56:57 mail MailScanner[25523]: Batch (1 message) processed in
117.39 seconds

CPU load stays on 99%.

In many cases I get a false "Denial Of Service attack is in message" for
plain text mails. Exactly the same behaviour I can see on two different
MailServers. My MailScanner Version is 4.55.10.

Plese let me know if you have similar observations or even solutions.
