Problem with shutdown #256

Open GoogleCodeExporter opened 8 years ago

What version of the product are you using? On what operating system?

Tell me more...

I've a problem with a memcached shutdown command. I reported my source:

InetSocketAddress scktAddress = new InetSocketAddress(host, 39999);
// Istance of memcached client
memcachedClient = new MemcachedClient(scktAddress);

// Store MyKey
memcachedClient.add("mykey", 0, new String("myvalue"));

.... other add/delete keys

At the end, when I finished to write and read in memcached area, send shutdown 
command:

memcachedClient.shutdown();

I receive this error message:

What is the meaning of the phrase: "No IO while shut down", as I have finished 
the process of writing and reading.

Thanks in advance,

This means that we tried to handle IO while the connections were in the process 
of being shutdown. The fix for this should be trivial.

Is this still an issue with the latest libraries?
