TMM Restarting (OS Version 12.1.1)
The technical support for this OS device has been out of support (Technical EOS at 2021), so we cannot open TAC to support.
For now the log still appear :

The Traffic Management Microkernel (tmm) process may restart without a stack trace or core file after becoming disconnected from the Master Control Program Daemon (mcpd) process.
This issue occurs when all of the following conditions are met:
- The Linux kernel memory becomes fragmented.
- Another memory-intensive operation occurs, which may include:
- You perform a configuration synchronization (ConfigSync) with full reload.
- You run a tcpdump session.
If tmm fails to start or restart properly as a result of this issue, you can try to recover the system temporarily by restarting the BIG-IP system.
