Bug #66350 for AnyEvent-Memcached: AnyEvent::Memcached not handling unavailable memcache servers correctly?

I have a test script (attached, hopefully RT will do the right thing with it) where I'm setting up two memcached daemons and connecting AnyEvent::Memcached to both of them. I then run loop over a sub that checks for a set of keys 1-10, and if any do not exist, it creates them. This runs fine. However, what I wanted to test was the failure of one of the memcached. So in my shell, I kill one of the memcached instances. AnyEvent::Memcached seems to then hang on the 'get' looking for all the keys. The debug output gives this: Disconnected 127.0.0.1:11212 AnyEvent::Memcached::Conn=HASH(0x93c5f64) Error: Broken pipe at /home/y/lib/perl5/site_perl/AnyEvent/Connection.pm line 257.

Then it repeats this message forever: Connecting to 127.0.0.1:11212... at /home/y/lib/perl5/site_perl/AnyEvent/Connection.pm line 243. Not connected 127.0.0.1:11212: Connection refused at /home/y/lib/perl5/site_perl/AnyEvent/Connection.pm line 266. I would expect there to be a timeout for io operations that would simply take the server out of the connection pool like other clients. Is this a bug or am I supposed to implement my own AnyEvent::Memcached::Hash subclass that handles this? My memcached is 1.4.5 and I'm using AnyEvent::Memcached-0.05 on perl 5.8 and perl 5.10 (same problem on both). Jay Janssen High Availability Something-or-other jayj@yahoo-inc.com
