Occasionally, tmsh processes are orphaned when a user connects to the BIG-IP system via SSH, runs commands, and then quits the session or disconnects. An orphaned tmsh process will have a parent pid (PPID) of 1. You can check for orphaned tmsh processes using the following shell command: /bin/ps -o pid,ppid,comm -C tmsh PID PPID COMMAND 8255 1 tmsh If this issue occurs often enough, it might cause the BIG-IP system to run out of memory.
Orphaned tmsh processes are created, which might eventually lead to an out-of-memory condition, if it occurs often enough.
-- Using tmsh to connect to the BIG-IP system via SSH. -- Running commands. -- Quitting the session or disconnecting.
There are several workarounds for this issue: -- Change the default shell to bash for users that are going to use the script. -- Use iControl. -- Kill orphaned tmsh processes.
Tmsh processes are no longer orphaned when a user connects to the BIG-IP system via SSH, runs commands, and then quits the session or disconnects under these conditions.
