Unregister modsnap txns from crashed clients #4828

Closed morgando closed 1 week ago

morgando commented 2 weeks ago

There is a bug where a modsnap transaction isn't removed from the database's list of outstanding modsnap transactions if the client crashes. This holds up log deletion.

The changes in this PR expose and fix this bug.
