Hello!
I have a sensor IPS-4240 which holds IPS software 6.2(3)E4. Right now we havn't got a license.
With the device wh have almost 100% cpu usage all the time:
show statistics host

Command Control Port Device = Management0/0

totalBytes = 1984548864

end = 03:00:00 UTC Sun Oct 30 2011
CPU Statistics
Usage over last 5 seconds = 100
Usage over last minute = 100
Usage over last 5 minutes = 100
Memory Statistics
Memory usage (bytes) = 1426128896
Memory free (bytes) = 558419968
From service accont I see that only one process eats CPU - mainApp.
I even created addition virtual sensor vs1 where I have disabled all signatures. It gave me no result.
Situation can be changed for a while after the sensor's reboot, but not for long time.
show interfaces doesn't show a lot of input traffic too.
Event log contains only following warnings:
evError: eventId=1293461883161643337 severity=warning vendor=Cisco
originator:
hostId: XXXXXX
appName: notification
appInstanceId: 409
time: 2011/01/19 15:22:56 2011/01/19 21:22:56 GMT+06:00
errorMessage: name=errWarning - the subscription lost data [IdsEventStore::readSubscription()]
What can be a problem? How can I reduce CPU usage?
With hope to resolve the issue

It would be difficult to pin point what the exact issue is with the high CPU just by the information provided in the post. It seems that the mainApp is causing the high CPU, however, it is worth investigating further. I would suggest that you log a Cisco TAC case so further investigation can be performed.
Alternatively, you can try to upgrade the software to the latest version of 7.0.4(E4) which has engine improvement.
