Not sure what happened to my installation but when I try to fire up my grin node (v4.0.0-beta2 and v 3.1.1) I get the following:
// grin-server.log
thread ‘main’ panicked at ‘called Result::unwrap() on an Err value: IOError(Os { code: 35, kind: WouldBlock, message: “Resource temporarily unavailable” })’: src/bin/cmd/server.rs:61 0: backtrace::capture::Backtrace::create

What got corrupted?
