Hi louis.williams, nothing else is required as of now from the execution side. Thanks!

Scope: Disable the mongoDB test.

 

Also please verify if WT-6694 can be fixed or not.

The memory leak is coming from searching metadata during recovery phase followed by a shutdown. This is a known issue tracked by WT-6694: when there is a panic error during recovery phase,  WT can leak memory allocated for pages in cache during connection shutdown.

This ticket can be used to disable the MongoDB test until WT-6694 is fixed.
