spamassassin memory usage

[nars]

I would like to hear from others experience about using spamassassin, I heard it may consume lots of memory, is it still the case in latest versions? is it worth using it?

For if there is a large spam attack - too many processes are started and the system can run out of resources. In this case one of the suggested solution you can find here: http://faq.swsoft.com/article_123_787_en.html
Probably following thread can be interesting for you also:

Thank you for your reply.

Just a question, what's the disadvantage of lowering SPAMASSASSIN_MAX_CHILDREN? Just a supposition: if I set it to 1, messages will be processed by spamassassin more slowly (like being put in a queue to be processed each one at a time, all by same spamassasin process...) or will they just bypass spamassassin check if some other messages are being checked at same time?

In this case messages will be processed by spamassassin more slowly. But all messages will be processed. Actually, qmail will start more qmail-local processes in this case, if spamassassin won't be able to process all incoming messages. The number of messages which can be delivered locally at once is limited by 10 by default but can be set with help of /var/qmail/control/concurrencylocal parameter. If you don't have this file you need to create it and put desirable value.
