We have a SourceFire 3D8140 which is managed by a virtual defense center (FSMC). It is showing high high memory utilization (about 97%) on 8 of it module CPU usage. The appliance has 5.4.0.7 (Build 40) firmware and the FSMC has 5.4.1.6 firmware. Can someone please tell me whether it's a know issue or not? We have another non-prod appliance, same everything. That one doesn't have any issues like that.
