Opened: Mar 28, 2019
Severity: 2-Critical

Symptoms

Overly strict internal validation can cause TMM to raise an OOPS when it does not need to.

Impact

Traffic disrupted while tmm restarts.

Conditions

Device instability.

Workaround

Set 'tmm.oops' to a value other than 'panic': tmsh modify sys db tmm.oops value silent tmsh modify sys db tmm.oops value log

Fix Information

Loosened internal validation so OOPS does not occur.
