My instance just crashed on this out of nowhere. It seems like this is a condition that can happen when two or more sockets gets disconnected at the same time. Each one triggers
socket close
, and for each of those we remove the socket from oidentd which in turn refreshes the oidentd config file. Once we're in there refreshing the database, we trip on the other closed sockets we haven't cleaned up yet, which in turn crashes the whole server.I have a handful of users on my instance, with at least one server in common so one server restarting would cause a handful of closed sockets on the same tick which would trigger this race condition. At last this is the only plausible explanation I can think of for this happening.
Switched it to just log and skip it instead of an exception.
