Can you do 'show lockchain <pid>' for the two threads blocked on locks next
time and include that output. The two threads from the ps above are:
772 705 772 0 Ls *rtentry 0xffffff0003be5640 sshd
22 0 0 0 LL *rtentry 0xffffff000104e640 [swi5: +]
16 0 0 0 LL *inp 0xffffff00085726e0 [swi4: clock sio]
772 and 22 there might be a potential deadlock in fact.
If you can reproduce with WITNESS and get 'show locks' that might help, too.
Either that or get a core dump for use with gdb.
