WebSocket textAll() causes kernel panic

[SoundsSerious]

Hey! Been loving how amazing this webserver is, however I'm running into a problem when I'm trying to send telemetry data at a very fast rate. I assume the following stack trace is due to some sort of low memory kernel panic.

I am having a very similar problem with a large data rate as well, I'm sending packets about 60 times a second, It seems the Async server is not processing them fast enough and I am running out of heap :( Is there anyway to force a websocket.textAll to process immediately?
