Last Modified: Apr 17, 2024

Opened: Jan 13, 2023

Severity: 3-Major

Symptoms

On repeated addition and deletion of the virtual and LSN Pools, TMM crash can occur.

Impact

TMM crashes and causes the processes to restart.

Conditions

When an LSN Pool is used in a VS, the code creates an internal listener with the same name as the pool. When the VS and the Pool have the same name, it results in two duplicate listeners. When the LSN Pool is deleted and recreated with the same name, it causes the TMM to crash.

Workaround

Avoid creating an LSN pool with the same name as the virtual.
