It appears you have corrupt data in Mailman's locks/master-qrunner file.

Assuming there are no mailman processes running at all, you can just
'rm locks/*' and that should avoid the problem.

Note that a typical mailmanctl lock is a pair of files named




each with contents

/path/to/locks/master-qrunner.<hostname>.<pid>[user at host locks]

In your case, it appears that the lock files exist, but a numeric <pid>
can't be parsed from the contents.
