OS: Linux
I am getting following exception when connecting to Memcached server.
I did some local test in which I created 200/300 threads and I started
getting connection errors, any idea?

Exception
java.io.IOException: Too many open files
        at sun.nio.ch.IOUtil.initPipe(Native Method)
        at sun.nio.ch.PollSelectorImpl.<init>(PollSelectorImpl.java:40)

net.spy.memcached.DefaultConnectionFactory.createConnection(DefaultConnecti onFactory.java:
153)
        at net.spy.memcached.MemcachedClient.<init>(MemcachedClient.java:186)

Also I am getting the following exception,

net.spy.memcached.OperationTimeoutException: Timeout waiting for value
        at net.spy.memcached.MemcachedClient.get(MemcachedClient.java:1185)
        at net.spy.memcached.MemcachedClient.get(MemcachedClient.java:1200)

Seems like spymemcahced has lots of issue, there are lots of post
which has time out exception - is the memcached client related or its
the memcached itself or its network issue?
