tmm leaks memory in the ECM subsystem.


With this configuration in place, tmm leaks memory each time the configuration is modified. tmm eventually runs out of free memory. This initially impacts traffic and might eventually lead to tmm crashing and restarting. Traffic disrupted while tmm restarts.


-- You import one or more SSL certificates onto the system. -- The SSL certificates names contain the 'ca-bundle.crt'. For example, 'my-ca-bundle.crt'.


You can work around this issue by renaming your SSL certificates so that their names do not contain the 'ca-bundle.crt' string.
