Severity: 3-Major


Under certain circumstances, the Traffic Management Shell (tmsh) can consume more system memory than expected.


Various delays may occur in both command-line and GUI response. Extreme instances may cause one or more processes to terminate, with potential disruptive effect.


Multiple users or remote processes connecting to the BIG-IP administrative command-line interface.


For users with administrative privilege (who are permitted to use the "bash" shell), the login shell can be changed to avoid invoking tmsh when it may not be needed: tmsh modify /auth user ADMINUSERNAME shell bash
