<BR>
We are using the OpenSIPS server with MSRPRelay and we see this strange behaviour. Usually, we can successfully create and destroy MSRP streams<BR>
but at some point we try to create multiple MSRP sessions almost smiultaneously and some of them fail with a “Internal server error” response.<BR>
In the server logs we have these messages:<BR>

On the server side we have OpenSIPS server working over TLS, also we have MSRPRelay working on TLS. On the client side we are using sipsimple.<BR>
