 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.
