Hi All,

Running Snort 2.9.3 on freebsd 9.0.

Looking at the Sonrt's pref. data show 80% packet drop and no data
processing in irregular intervals.

Turned on PreProcessor Profile stats that shows the PCRE "Checks" and
"Exists" differ (99% did not "exit").

The snort.conf file has no "pcre_match_limit" or
"pcre_match_limit_recursion" configured.

The server is not stressed out and have enough free memory.

Did anyone came across similar problem ? any suggestions ?
