Unexplained IO exception...
September 13, 2010 11:20PM
Hi all,

We are using memcached in our application for caching some custom
value objects. It is deployed on a Linux box.

However, this morning, I am getting an IO exception, as follows, when
the client tries to make a "get(key)" call. After this error, every
request takes a long time (close to 4-5 seconds) and it does not seem
like the response was located in memcache.

2010-09-13 00:40:10.303 INFO net.spy.memcached.MemcachedConnection:
