Symptoms
Memory usage increases on Security Gateway (can be seen in the output of 'fw ctl pstat | grep -i "memory used"' command).
Proxy is located behind the Security Gateway.
Long connections can be seen in the Connection Table (refer to 'TimeStamp' in sk65133).
Memory leak detection procedure (sk35496) does not show any leaks.
Cause
The Anti-Virus is handling HTTP connections that have multiple sessions and does not free the memory allocated for these sessions, even after they are being closed. The sessions' resources will be freed only after the connection ends.
