The code as presented is confusing to me. That may be my fault as I am no authority on event loops. However, since nobody else has replied yet it may be that they are confused as well. If you could maybe address these questions I have then it might encourage others to chip in too.

  1. You are using both IO::Async and AnyEvent but not using either of the glue modules I would expect to see (AnyEvent::Impl::IOAsync or IO::Async::Loop::AnyEvent). Could you explain this?
  2. The code appears to want to ping the same set of hosts twice on different schedules. I cannot think of any reason to do this. What is your intention here?
  3. Within each timer you are pinging 254 addresses 4 times with a 2 second timeout on each. Any target which drops the packets will therefore take 8 seconds to complete. And yet your timers are each on a hard reschedule of less than 8 seconds. Even if your code worked without blocking you could end up with a ping bomb. Again, without knowing your intention it is hard to advise further.

If you could give a clear statement of your intended algorithm it would help me (and maybe others) to be in a position to help you more.

Update: removed reference to IO::Async::Loop::AnyEvent as newer versions of AnyEvent explicitly prevent its use.
