java.lang.IllegalStateException: Timed out waiting

[GoogleCodeExporter]

What version of the product are you using? On what operating system?
Memcached-2.5.jar. SunOS and windows 

Tell me more...

Most often I get the below error while deleting the data from Memcached. So, I 
use MemcachedClient.flush command and it works fine. 

org.civ.architecture.batch.ModuleLaunchException: Exception in 
Memcached.deleteData()
+ java.lang.IllegalStateException: Timed out waiting to add 
net.spy.memcached.protocol.ascii.DeleteOperationImpl@14e45b3(max wait=10000ms)

below is the method which will be called to delete the data.

public void deleteData( String key ) throws MemcachedException
{
  if( mem != null )
  {
    try
    {
      MemcachedClient.delete( key );
    }
    catch( Exception e )
    {           
      throw new TestException("error in memcached");
    }
  }
}

I get the below warning messages and errors out. I am not sure whether there 
are lot of records in Memcached which causes this error while deleting the 
existing records from Memcached.

2.5 is very, very old at this stage.  I don't think we'll be able to go back to 
2.5 to look at this.

Is there anything in the log prior to this-- perhaps something about the 
connection being dropped?

• Changed state: NeedInfo

[GoogleCodeExporter]

The client connection is dropped after it throws the exception. As per the 
error it tries to reconnects. Connection state is also changed but suddently it 
drops the connection specifying "7060 bytes remaining to write". Is this issue 
similar to issue nbr = 192? Becos, this happens when I try to load huge amount 
of records and deleting 1 record at a time.

I will upgrade to "spymemcached-2.7.3.jar" and test it.
