During regular firewall health check , I found one Check Point firewall cluster has a abnormal virtual memory usage from System Counters - System History view. The cluster is 5600 Security Appliance.
It looks the memory usage is going up significantly recently. There is no recent changes on hardware, software and configuration except normal firewall changes. I am afraid of Check Point gateway will freeze after this counter reached certain high number based on some SKs such as sk66482, sk110362,
sk35496 has a bunch of methods to detect memory leak. In my this case, the fix was simple, just installed a latest Jumbo Hotfix 205 for R77.30.
