CPU spikes caused by ipsengine

Hello all,

I've problem with spikes in CPU caused by the ipsengine process.

This is a huge problem during video-meetings/calls.

Each time the CPU spikes the traffic is dropped for 1-3 seconds.

I run FortiOS 6.2.3 and below is how it looks like.

 ipsengine    24908      R <    61.8     3.4

 ipsengine    24908      R <    99.5     3.4

 ipsengine    24908      R <    99.9     3.4

 ipsengine    24908      R <    99.9     3.4

 ipsengine    24908      R <    99.9     3.4

 ipsengine    24908      R <    99.9     3.4

 ipsengine    24908      S <    68.8     3.4

Anyone seeing the same thing?

Any suggestions?
