Shutdown qmail, check for stale file handles (using lsof or fuser) and
do an fsck on the filesystem. I had similar issues which turned out to
be a broken handle ruining the directories inode.

OK, it's not qmail-local but rather a program called by the relevant
.qmail

I'd personally strace or truss the process id, you should see what the
last syscall was and to what, so that may give a clue as to what it's
doing. If it's socket related then you may have to kill one and strace
-ff qmail-send and then trace the newly hung program that qmail-local
spawns.

Hope this helps.

It was a MySQL "Too many connections" problem
