This just happened to me again:

A total of 282 processes are hung on this file
This process has the lock:
root@mail:/home/schu# strace -p 27029
Process 27029 attached - interrupt to quit
futex(0x7f6ff0a7a720, FUTEX_WAIT_PRIVATE, 2, NULL
When I kill it with TERM I get:
) = ? ERESTARTSYS (To be restarted)
--- SIGTERM (Terminated) @ 0 (0) ---
Process 27029 detached
Then my process list starts shrinking as the other 281 processes close out.
I should note that the mailboxes this happens on are being monitored by
multiple users so there are multiple connections to this mailbox and the
others that have had this problem.
