| Description |

In BF-9986, we saw many threads waiting on DB locks, but the hang analyzer cannot generate the graph for us. The lock manager dumps the information though.

The mongodb-show-locks command is similarly not showing any output either. I also don't see any "Ignoring GDB error" messages that I believe the find_lock_manager_holders() function simply isn't finding them. The changes from c7bd92f as part of The find_lock_manager_holders() had assumed that it is with the string it searches for in the frame and the concrete type it looks up.
Note: The issue isn't specific to Amazon Linux 2 so I'm changing the title of this ticket. |
