Severity: 2-Critical


If virtual servers which have HTTP2 or SPDY profiles are updated, then the TMM may leak memory.


The TMM leaks memory, and may take longer to execute future configuration changes. If the configuration changes take too long, the TMM may be restarted by SOD.


-- A virtual server has a HTTP2 or SPDY profile. -- Any configuration object attached to that virtual server changes.



Fix Information

The TMM no longer leaks memory when virtual servers that contain a HTTP2 or SPDY profile are reconfigured.
