I've installed the last build(3021) on my server yesterday and I've got similar problem.
My server console spams "Warning: NET_Sleep: select() syscall failed: Interrupted system call", which causes server overload and eventually shutdown.
I can't even restart the server then via control panel after that. My server is hosted by Luxhosting.
If there's a solution for this I'd be happy to hear it. If there's no such solution, then I'd request the last build where this error doesn't occur.
Best regards,
Tommy
