Above, digest runner was interrupted in processing and shunted the message it was working on.
and below, pipeline runner was interrupted in processing and shunted the message it was working on.

The above says the runner was doing a database lookup. This may be a coincidence or there may be some database locking issue that underlies the issue with the pipeline runner.

I suggest doing the following assuming your Mailman database is not sqlite3 (if it is, just do step 2):
- Stop mailman core and maybe other mailman services too.
- Assuming the two shunted messages are still in Mailman's shunt queue,
run
mailman unshuntto unshunt them. If there are more shunted messages, inspect them withmailman qfileto see if you want them, They may be spam. - Restart your database server.
- Start Mailman core and any other stopped services.
Also, look in the database server logs for any issues.
