A memory leak occurs when APM application tunnels or AM iSession connections are aborted while waiting to be reused.
Available memory might be significantly reduced when a large number of iSession connections waiting to be reused are aborted.
The iSession profile reuse-connection attribute is true. A large number of iSession connections are aborted while waiting to be reused.
Disable the iSession profile reuse-connection attribute. Restart TMM.
