It's not a memleak.

It's stream4, conversation and portscan2.  They track connections and need
a lot of memory to keep all the info in.  You can change the memory usage
by setting the 'memcap' options in snort.conf for the preprocessor(s) in
question.  You can also drop the number of conversations that are stored
by using 'max_conversations'


Any place to find "reasonable" numbers for these settings. I have two
snort-daemons and each one (in default-config) eats up to 60MB Ram
which is imho too much.  If I reduce them to 10MB : would this
decrease securitylevel then cause less conversations can be monitored
?  And after all : what values should I set to gain maximum
performance and using not more than 10-15MB. (Or do I ask for the
impossible ?)

thnx,
