User have two Cisco ASA5540X firewalls with IPS modules configured in a failover pair. Behind this firewall pair (on the inside) are about 140 hosts that use various web-enabled applications, minimal Internet, some email (maybe 10 hosts), and some light file-sharing/access. My IPS is configured for inline analysis, but I have noticed that the cpu runs 100% all the time (6 cores).
Since I don't want any traffic by-passing the IPS, my configuration on the firewall looks like this
This is one of the issues which is lately seen on the TAC and yes, it is related to the java version on the PC because of the JAVA SSL Client Hello Format. Java downgrade should fix this.
Go to control panel->right click java->Open->Advanced->Check all boxes under debugging and click radio button for show console
Although I have installed a handful of these and all of them have had a a CPU load of 100%, I was told by support that the CPU load on an IPS is very inaccurate way of determining load, it is much better to use the inspection processing load. After further digging I found this - the issue is discussed as part of this bug - CSCtl74475
