Opened: Aug 03, 2021
Severity: 4-Minor

Symptoms

Modifying sys db key log.dosl7.all.level or log.dosl7.datasync.level to Informational enables debug level message written in /var/log/tmm log file. Depending on the amount of the message and system resources available at the time of the debug messages, tmm might crash.

Impact

Unintended debug messages fill /var/log/tmm log file. Depending on amount of the message and system resource at that time of the debug messages, tmm might crash. Traffic disrupted while tmm restarts.

Conditions

Tmsh modify sys db log.dosl7.all.level value Informational or tmsh modify sys db log.dosl7.datasync.level value Informational

Workaround

Set the db keys to the default. tmsh modify sys db log.dosl7.all.level reset-to-default tmsh modify sys db log.dosl7.datasync.level reset-to-default

Fix Information

None
