KB #787 - How do I limit the maximum children for spamd? For if there is a large spam attack - too many processes are started and the system can run out of resources.

RESOLUTION

In Plesk 7.5 and 8.0 you can limit the number of simultaneously running SpamAssassin processes with 'SPAMASSASSIN_MAX_CHILDREN' option in /etc/psa/psa.conf:

SPAMASSASSIN_MAX_CHILDREN 5

You can specify a desired value then restart psa-spamassassin.
If the line is omitted then the default value is 20 for SpamAssassin 2.6 and 5 for SpamAssassin 3.x.

Since Plesk 8.1 SPAMASSASSIN_MAX_CHILDREN option is obsoleted but this value can be managed through Plesk CP. Use "The maximum number of worker spamd processes to run (1-5)" on the Settings tab of Server>SpamFilter page. The value is stored in 'misc' table in'psa' database:

#  mysql  -uadmin -p`cat /etc/psa/.psa.shadow ` psa -e "select * from misc where param='spamfilter_max_children'"
+-------------------------+-----+
| param                   | val |
+-------------------------+-----+
| spamfilter_max_children | 5   |
+-------------------------+-----+
