Memory leaks #160

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
I've got the next problem during stoping tomcat.

SEVERE: The web application [/todo] appears to have started a thread named 
[Memcached IO over {MemcachedConnection to localhost/127.0.0.1:11211}] but has 
failed to stop it. This is very likely to create a memory leak.

Did you actually attempt to shut down the client when you were done with it?

You wrote code that creates a MemcachedClient object.  Did you also write code 
to call .shutdown() on that object when it is no longer needed?  If not, that's 
what the above is complaining about.

Hmm, I'm thinking how to catch a moment (when tomcat is stoping web 
application) and call .shutdown()...

The way to use every time a new instance of memcached client is not ideal.

Whatever application hook you used to set it up surely has a similar hook to 
tear it down.  I do this in my own applications with a ServletContext.

I'm going to close this as a bug.  We can continue the conversation, but the 
functionality is present to do this.
