We run several IDS/IPS in our clients network and for the most part they run very well. The IDSM-2 modules however experience a 10-30% missed packet percentage during heavy loads and it seems as though it never recovers. My workaround is to disable a signature then immediatly re-enable that same signature. You lose the sensor for a minute but after the engine reconfigures itself the mpp issue is resolved. Until another period of heavy traffic. I have left it run missing 23% for 24 hours and the sensor did not recover. But after the above workaround it ran fine until the next day when it got slammed again. I have tried reducing the traffic that the sensor sees and it didn't seem to help. Anybody else had this or a similar problem?
