failback is not working? about memcached-java-client

[bill2004158]

the log is:

log.error("++++ failed to get SockIO obj for: " + host);

can you add error msg in the logger.
so we can make sure why connection fail.

In 2.5.x, failback and failover and mocked in our real implementation. Since due to our investigation, we found it slow down the performance.

DirectBuffer can increase the performance, while if the memcached server crashed, it will always allocate direct buffer and wait for the gc of VM. It will finally cause OutOfMemoryError.

In version 2.6.0, we enabled the log of detailed error information, but we still didn't add failover support.

Since if we do like this, it will never failback. While in current implementation, failback is automatic.

If we get rid of the direct buffer, we can solve the OutOfMemoryError. We will do a deep investigation for this issue.

Thanks anyway for the information.

Hi bill2004158,

We add "failback" support in release 2.6.1 which you can download and have a try.

We also re-implement the connection pool based on Apache commons pool in this release and OutOfMemory error disappeared in our test.

Really thank you for your suggestion.
