Insufficient Comunication Memory Pool

Question

I keep getting this message

Insufficient memory in pool: Communication. Attempted alloc size: 28 bytes. (Global)

in the profiler when connecting to our game, I've tried open a brand new Wwise session and connect the profiler to the game and the memory usage is below the limit. So I think there's something in my session that keeps accessing Communication memory sort of like a memory leak or something...Do you guys have any clue of what might be happening here?

Answer 1

We just fixed such an issue on our project. It had nothing to do with the Communication Pool size. The sound bank (.bnk) simply wasn't loaded!

The weird thing is: if any non-streamed sound gets played, the bank is automatically loaded. But not for streamed sounds. So having a sound effect from this bank playing at any point before your music can change the whole thing.

Answer 2

This might not be exactly your situation, but I hope it will help you figure out you problem.

As far as I know, communication memory pool size has nothing to do with the runtime memory usage by gameplay. So it might not be caused by memory leak.

I started getting the same messages months ago, and each time I got this message the soundbank and memory profiler would stop working. At that time I simply set the communication memory pool size to larger numbers in Communication Settings in ue4 of Wwise until the messages are gone.

What was a problem is that, our project used to load all soundbanks in ue4 editor, so the set Maximum Number Of Memory Pools is very large. I gradually felt that it might be the reason why I keep getting those annoying messages ( Since the maximum number of memory pool is getting larger, the communication between game engine and wwise profiler will also need more and more memory to communication that information).

After a few weeks, we stop loading all banks in game engine editor. So I set the maximum number of memory pools to a much smaller value(255). And set the communication memory pool size to 1Mbyte. The message no longer appears and the soundbank and memory profiler returned to be working.
