The Traffic Management Microkernel (TMM) process may produce a core file and restart when processing SPDY traffic. As a result of this issue, you may encounter one or more of the following symptoms: - The BIG-IP system fails over to the standby system if configured as a high-availability pair. - The BIG-IP system generates a TMM core file to the /shared/core directory.
Traffic disrupted while tmm restarts.
This issue occurs when all of the following conditions are met: - You associate a virtual server with a SPDY profile. - The virtual server processes a SPDY client connection with more than two concurrent streams. - The SPDY client connection stalls and is subsequently aborted.
This issue has no workaround at this time.
