I've seen this happen while deleting filespaces.  Usually when I try to
delete too many at once or when clients are accessing the server while I'm
doing the deletes.  If this is the type of operation you are performing when
the deadlock occurs, try the operation again with fewer simultaneous deletes
and perhaps the problem will disappear.

I'm a fix it rather than figure it out kind of guy.
