Hello,

I’m not exactly sure of the repro steps yet, but basically, after a couple of times hitting the play button, all the subsequent plays raise an error because the network port for live update is in use. Disabling live update “fixes the issue”, but that’s obviously not a real fix.

We don’t even have the fmod profiler connected or any fmod studio editor instance running. In my case, I only have Unity 2019.2.10 with the Switch as target, Visual Studio 2017 and a couple of programs that don’t use port 10048 afaik.

What version of the FMOD Unity Integration are you using?

I was using 2.00.04 but I recently upgraded to 2.00.06. I’ll let you know if the problem still happens.

Still happening. Very annoying with error pause turned on…

I have not been able to reproduce that issue here. Each time you play-in-editor do the FMOD memory values, in the Debug window, keep going up?

I am getting the same error after the update (I actually did a fresh install, so no prior settings were kept and just “ported” over).

These are my settings in the inspector:

 ![image](https://canada1.discourse-cdn.com/flex036/uploads/fmod/original/1X/660f451227aac9c8969663cf33bc02bd85c89eaa.png)

Curiously the errors are gone after a restart, but I still got them on video (albeit without the debug overlay, sadly) from a couple days back. My guess is that some other service already occupied the port. Would FMOD be able to use a different one in that case?

Edit: It just started happening again, no memory usage going up though. ~~Interestingly, a “netstat” call does not show any process listening on that port…~~ Interestingly, the Process Monitor lists the port 9264 as being occupied by the Unity editor. Is something not cleaning up properly? (this might happen during an assembly reload when changing scripts while the game is running)

If this was caused by the FMOD Systems not being cleaned up properly, you could expect to see the memory usage increase each time a new system is created.

Could you try changing the `logging level` in the settings to `LOG` and attach the log file here after running it again.

As far as I can remember the usage actually did go up, but only after hitting the play button again and again and again. Will attach the log tomorrow.

Hello ! Has this been fixed by any chance ?

I still get the exact same issue.

Thank you 🙂

What versions of FMOD and Unity are you using?  
Are you able to share your output logs?

I’m using FMOD 2.01.08 and Unity 2020.3.16 LTS.

Here are my logs : [https://we.tl/t-yEoRWd6SAv](https://logs) (Unity Editor and FMOD Studio)

EDIT : Just wanted to add that I took a while to reply because it miraculously worked again for a few days, and this morning, just back again.

Thanks for the logs, it definitely looks like something is holding on to to the default port.  
Do you see memory usage growing in the FMOD Studio Debug window? Does the issue reproduce with a different Live Update Port value after a couple of playthroughs / editor shutdown and reopens?

I’ve started getting this also with the latest version of everything (plugin 2.01.11 it looks like) on PC.

**EDIT:** what I’m getting is “Cannot listen for connections, port 9264 is currently in use”, I’m not sure if it’s exactly what OP is referring to, but feels similar.

FWIW I traced back the listening application with netstat, and it looks like it is the Unity.exe process that is listening on that port. I’m not sure if this helps 😉

Also, I’ve been doing a bunch of game starts/restarts/crashes/assertions (unrelated to FMOD) using Visual Studio. Looks like some destruction code may have been skipped by a game crash (?).

Thank you!

Thank you for the extra info, that specific error is bubbling up from the Core API- and I’m guessing you aren’t getting anything like “FMOD.Studio.System.Release”, “closesocket failed” or “Closing client connection” anywhere?

OK it seems to have gone away with the latest reboot; it looks like it got confused between starting/stopping sessions quickly (or before it was ready). I will keep my eyes peeled for this for better repro cases if they happen. Thank you!

Hello, i’m getting the same issue here :  
UNITY 2021.2.2f1  
FMOD 2.01.05

I can launch unity and play one time, connect with FMOD and the profiler is working correctly.  
But if i stop unity and hit play again i get either :

- “[FMOD] FMOD\_OS\_Net\_Listen : Cannot listen for connections, port 9264 is currently in use.” error in Unity. FMOD continue to show “live update on” but isn’t getting any data

- no error message in Unity, FMOD continue to show “live update on”, but if i hit record in the profiler, Unity crash with this in the log :“Got a UNKNOWN while executing native code. This usually indicates a fatal error in the mono runtime or one of the native libraries used by your application.”

the second time i hit play i have a log “FMOD destroying systeme instance” before the log of creating a new one… the memory is not going up in the debug window while playing…

Other port do the same and i’m not getting any log about "“FMOD.Studio.System.Release”, “closesocket failed” or “Closing client connection”

Update to my previous message:  
I updated FMOD to 2.02.03 ( keeping Unity 2021.2.2f1) = same problem  
i made a new project from blank , add a listener and my main Banks = same problem …

I have truly no idea on how to fix this .

Do you see memory usage growing in the FMOD Studio Debug window?  
While Unity is closed, if you type `netstat` in the command prompt does 127.0.0.1:9264 appear in the list?

Thanks for the reply:  
Memory usage stay consistent.

For netstat i have 2 scenario were i found this bug:  
(UNITY 2021.2.2f1 , FMOD 2.01.09)

Scenario A:

1. Unity Setting to PLAY + Fmod Setting Live update on ON

- TCP 127.0.0.1:65499 www:9264 ESTABLISHED

1. Unity Still Playing + Fmod Setting Live update on OFF

- TCP 127.0.0.1:65499 www:9264 TIME\_WAIT

1. Unity Setting to STOP + Fmod Live update still on “OFF”

- TCP 127.0.0.1:65499 www:9264 TIME\_WAIT

1. Unity Setting to PLAY again + Fmod Live update still on “OFF”

- no port 9264
