It was fixed fairly quickly to be fair, with an external restart thingummy. Quite why it occurred is a bit of a quandary though.

had servers respond to ping but not ssh before. Had a case where some apache processes were getting hung and never exiting. So ...

... eventually ran out of file descriptors. Had to bump server.

okay, that's probably way too verbose...
