Bottom line is, this feature isn't fully tested.  We see it as experimental.

Stream5 track_icmp is disabled by default in snort. Why?

README.stream5:
"ICMP messages are tracked for the purposes of checking for unreachable 
and service unavailable messages, which effectively terminate a TCP or UDP 
session."

Isn't this a good thing, to let snort bail early on TCP/UDP streams that 
are terminated and this is informed via an ICMP message?
