This should go in the stream5 preprocessor configurations section. A good indication to look for is the "S5" at the 
start of the message.

Subject: [Snort-users] memcap limit error

I'm seeing the following error messages show up (/var/log/messages).

May 31 14:02:06 sysabc snort[10890]: S5: Pruned 5 sessions from cache for memcap. 812 ssns remain.  memcap: 
8386339/8388608
May 31 14:02:06 sysabc snort[10890]: S5: Pruned 10 sessions from cache for memcap. 803 ssns remain.  memcap: 
8381933/8388608

I believe I need to increase the memcap setting, however, I am uncertain which entry in the config file(snort.conf)  
needs to be increased.  It is unclear to me which one is causing the error.  Help please!


Here are config file settings (all are at defaults) with memcap:

# DNP3 preprocessor. For more information see README.dnp3
preprocessor dnp3: ports { 20000 } \
   memcap 262144 \

# Reputation preprocessor. For more information see README.reputation
preprocessor reputation: \
   memcap 500, \
preprocessor dcerpc2: memcap 102400, events [co ]
