To Reproduce
Not sure how to reproduce. Is it due to server load? Or reconnect issue where the client is sending messages while the connection is waiting for validate token response?

Expected behavior
html5 server should send a properly formatted or complete message.

Actual behavior
Messages are not processed correctly.

Additional context
Don't see any failures on messages from bbb-web and fsesl-akka. Only from html5 server.

hi there, something new about this? I' finding a lot of these messages on my app-akka logs....
Is this a problem? can I ignore?

This consideration seems to be really important :
"Is it due to server load? Or reconnect issue where the client is sending messages while the connection is waiting for validate token response?"

Can anybody say more? thanks
