Not sure whwt the relevance of that is, but in general, you have to stop a
watcher when you close a fd.
The documentation epxlains this in detail.
However, this would not cause the problems you see.
It really looks much more like you accessed the same event loop form
multiple threads, or had another bug in your program, such as not
initialialising the file descriptor number properly.
Without an example program showing the issue or a minimal amount of
additional info (libev version, strace), there is nothing more that I cna
