KMS crashes on 23rd one-to-one call

[kyris9]

Hello. I know this is a long-shot but adding this issue just in case anyone is still watching this repository and can provide some help.

I tested kms-windows on a Windows Server 2012 R2 VM (8 processors, 8 GB memory) and used Node.js for Kurento's one-to-one tutorial page. I used 4-5 machines to simulate clients using Chrome's and Firefox's fake video streams. I could successfully establish 22 calls (i.e. 44 clients/browser tabs) but on the 23rd call, the media server crashed with the error (also attaching screenshot):
GStreamer-WARNING **: failed to create thread: Error creating thread: Not enough storage is available to process this command.

I repeated the same test twice just to be sure and the same behavior was observed again on the 23rd call. The CPU and the memory usage of the server only reached 35%. No issues with storage space either. Can anyone help?

Thanks,
Kyris
