How can I find the reason of HANG with WinDBG? (C++)

I got the full dump using this command when the process doesn't respond and doesn't work.

procdump.exe -ma [PID]

Also, I tried to find the reason why this process showed strange behavior using WinDBG. But I'm just a WinDBG beginner, so I didn't get any hint from the FULL dump file. (Actually I can't understand a WinDBG message) Is there someone who can help me with this problem?

This is !locks command result.

This result says "NO LOCKS", right?

This is ~*k (all thread call stack) result.

My guess is that the second callstack deadlocked the other 14, or vice versa. You need to look if you anywhere in them take opposing locks, so that a thread that gets lock A doesn't wait for lock B held by another thread which is waiting for lock A.

It can also be that one of the network IO threads is deadlocking the others, specifically the only one that is not waiting for an event (all other callstacks are stuck in one of the wait-for-single or wait-for-multiple-objects functions):

0477ff5c 750e635c ntdll!ZwRemoveIoCompletion+0x15

0477ffd4 77de9f45 ntdll!__RtlUserThreadStart+0x70

But it's not running your code as it seems, so I don't know really.
