SpamAssassin 2.55 problem

[Nejc Skoberne]

Hi.

> Does anyone have SpamAssassin 2.55 working well?

I have MailScanner 4.21-9 and SpamAssassin 2.55 with latest Postfix.

Before I had a Celeron 533 with 64 MB RAM. My mailserver load is quite
low (maybe 80-100 messages per day) and it didn't work OK. System was
using about 100MB of SWAP space! SpamAssassin was timing out, mails
were stuck in the queue...

I upgraded to 320 MB RAM (I added 256MB) and since then everything
works just fine.

Mem:        319904     282456      37448          0      65060      49088

Swap:       514072          0     514072

These are the MailScanner processes - they indeed need a lot of
memory.

(There are also other services running on the server
(sshd, Samba, dhcpd, named, FreeSWAN, ProFTPd), but since
server is for my personal use, their resource usage is quite low.)

My question: Is this behaviour normal? Does MailScanner (and
SpamAssassin?) really need so much memory to work smoothly?

Thank you for your answer.

Best regards,
