That means your process is running out of filehandles, which was
immediately caught. There is little to nothing that AnyEvent can do about
this situation, you'd simply have to increase your ulimits or avoid
needing so many fds.

If you mean that the program should have stopped, then you can override
the $EV::DIED callback with a version that exits - by default EV reports
runtime errors and continues.

Lastly, you can use AnyEvent::Strict and/or AnyEvent::Debug for more
diagnosis.
