There is a memory leak when changing a policy that is in use by a virtual server.
Upon every recompilation a small amount of memory is leaked in mcpd. If a policy is recompiled many times this can lead to memory exhaustion within mcpd which in turn causes a mcpd crash and BIG-IP system restart.
When an LTM policy is being applied to a virtual server, the policy is compiled for efficient execution.
Memory no longer leaks when changing a policy that is in use by a virtual server.
