9999 is the pid of the process that set the lock. webserver is the name
of the host on which it is running. What process is this? Is it the
web server or one of its children or is it one of Mailman's qrunners?
If it is a qrunner, which one?

Yes, It seems something keeps locking the list for some reason. The
admin interface has to keep waiting for the lock to be relinquished.
The question is what other process keeps locking the list and why?

Also check Mailman's 'locks' log if there is one, and Mailman's 'error'
