The code in scanTimedoutTCPSessions() is this:
freeSession(thisSession, actualDeviceId, 1);
Can you print the contents of thisSession and post the output.
(it's either print thisSession or print *thisSession in gdb, I don't remember which...
Also, please add #define DEBUG and then #undef DEBUG around scanTimedoutTCPSessions()
(it's in sessions.c around line 251) and post the message log stuff too.
Thanks!
