Which locks are the Thread 1607 and Thread 811 waiting for? Which thread owns the lock?

Sorry, for the late answer.
I have looked through the code. According to the code:
Thread 1607: locks TCB -> INP_READ -> unlocks TBC -> unlocks INP_READ -> locks TCB (after that, nothing happens)
Thread 811: locks TCB in sctp_send_abort_tcb -> locks TCB_SEND (after that, nothing happens)
I cannot find the place in which Thread 1607 locks TCB_SEND, but it is highly likely that Thread 1607 holds TCB_SEND.

I'm working on removing the TCP_SEND lock (for reasons other than avoiding a deadlock). Let me finish this and it would be great if you could test, if the problem persists.
