Symptoms

TMM crashes with a specific ASSERT-based backtrace.

Impact

Traffic disrupted while tmm restarts.

Conditions

Requires an LTM listener with an iRule that has a RESOLV::lookup command querying for a TXT record and receiving multiple RRs.

Workaround

None.

Fix Information

TMM no longer crashes due to the behavior of the LTM listener with an iRule that has a RESOLV::lookup command when parsing its return values.
