Screenshare issues

Had a screen share on system 1, and was viewing the share from a webcam viewer on system 2. At some point, the webserver did the out of memory thing, and the log excerpt appears below. When I tried to generate a jstack, it had an error saying that jstack couldn’t connect to a channel to talk to it. Here’s the traceback with a bit of context before/after…. Hopefully this is somewhat informative?

The one thing that puzzles me is that I’ve had 5 screen shares in world at the same time, and no failures. This time it was just 1 avatar per system. So I don’t know what is causing it.
