IPS Engine Running at 95%-99%
Im expiriencing a similar problem, whereby one of our VDOMs in a 3000D FW with connects +- 50k users, max sessions is +-400k sessions, the CPU spikes at around 9am every morning when everyone is back at work, and this affects our filtering, but as soon as we disable SSL Certificate inspection, the CPU goes back to normal. SSL is configured to inspect only 443.
i have upgraded the IPS engine from 3.00430 to 3.00444, but this did not resolve the issue.
this only happens on one of our VDOMs, we have 7 VDOMs in total including the root VDOM which is the only that is running flow-based mode the rest are running in Proxy Mode.
what could the issue be?
