Opened: Dec 03, 2020

Severity: 3-Major


Temporary TMSH-related subdirectories and files located in /var/system/tmp/tmsh may not be properly cleaned up after a TMSH session is terminated. These files can accumulate and eventually cause disk-space issues.


The /var filesystem may fill up, causing any of a variety of problems as file-I/O operations fail for various software subsystems.


A TMSH session is terminated abruptly rather than ended gracefully.


The BIG-IP software includes a shell script (/usr/local/bin/clean_tmsh_tmp_dirs) which can be run by the system administrator to clean up excess temporary files in the directories /var/tmp/tmsh and /var/system/tmp/tmsh.
