Symptoms

Simultaneous stats query and pool configuration change results in process exit on secondary.

Impact

The primary restarts, and the slot goes down, resulting in potential traffic impact. The ltm logs display error messages similar to the following: -- err mcpd[29041]: 01070734:3: Configuration error: Configuration from primary failed validation: 01020036:3: The requested pool (/Common/CYBS-P-UBC-43) was not found. -- notice mcpd[8487]: 0107092a:5: Secondary slot 1 disconnected.

Conditions

Running parallel operations in tmsh/GUI or multiple tmsh operations on pool objects. For example, running 'tmsh show' command while simultaneously updating the monitor on the pool in the GUI.

Workaround

Use the absolute name of the pool in the tmsh command: /partition_name/pool_name.

Fix Information

TMSH command now automatically issues the absolute path by using the context for the current connection to MCPd, so there are no MCPd restarts in this case.
