here is a process dump of the hanged state
hope you can fix this
Thanks

What OS? What version of Fopnu?

are you doing anything when the hanging happens?

any other details that might help?

Thanks for the dmp file.

Just to clarify, by hanging, you mean the program stops responding until you force it closed, or just for a few seconds at a time?  If you let it sit for a minute or two, will it ever come back?  Does your CPU run at 100% during this time, or pretty much idle?

I looked at the stack in the dump file, and it's inside ntdll in a plain close() function, when the UPNP router discovery socket is closing.  I haven't seen this before, and the UPNP implementation is shared with Tixati, so it's running on a lot of machines.  Just to be sure I examined the code to see if anything looked strange, but didn't see any problems.

If it keeps hanging like this in version 1.32, which will be out in a matter of days, please post another dump file and we'll see if it's in the same exact spot, or maybe it will show there to be a local loop that I'm missing.

In the meantime, a work-around might be to disable UPNP (and manually port-forward on your router if you need to.)

its actually worse then that fopnu hangs and no matter what I do I can not force close it with taskmanger or console it just turns into a zombie with 0% cpu used an no threads running (checked with sysinternals process explorer) with fopnu in this state I noticed that foobar2000 starts behaving strangely/crashing, I assume thats because it uses upnp too
so far restarting the pc is the only fix

yes it also hangs on a freshly restarted pc with nothing else running

I also use tixati lot  and never encountered this even running it several days straight

I've always been manually forwarding ports automatic forwarding is turned off on the router  I just never bothered turning upnp off

turning off upnp seems to have worked no hang so far
