I am also having a problem in setting out the timeout value for the
memcached. I am using the following connection string for setting the
timeout value of 200ms.
const char* config_string = "--SERVER=127.0.0.1:22122 --BINARY-PROTOCOL
--CONNECT-TIMEOUT=200 --SND-TIMEOUT=200 --RCV-TIMEOUT=200";
Now in order to test the timeout values, I opened up a TCP socket over port
22122 pretending to be a fake memcached server. However, the server took
around 10 seconds to timeout. Can anyone tell me what is the problem in
this case? I am attaching the source file with this message.
