Thank you very much. I will add time-based saves.
One single shutdown hook means shutdown hook in zone extension, right?

I use addShutdownHook for every room extention to save some status in the room. But when i try to shutdown the sever, some shutdown hooks execute and some do not. How to ensure every room save their data? public class BaseRoomExtension extends SFSExtension { @Override public void init() { trace(getC...

In my app, logout did heavy database job. So i adjust the number of SystemController thread pool size. But in the Dump i saw all the SystemController are idle and log out event are running in threads like "pool-1-thread-4". So i wonder how should i adjust the config. I user server version ...

Thank you very much.
I use a remote DB to check user name and password, which would cost about 250ms in average. Should I move the user check to UserJoinZoneHandler, or should i write an extension to handle the user check?

I compared the server side log and client side log, and found normally server side should be 17 Jun 2014 | 05:22:24,299 | Session created: { Id: 21253, Type: DEFAULT, Logged: No, IP: 10.108.8.86:49065 } on Server port: 9873 <---> 49065 17 Jun 2014 | 05:22:37,192 | (com.aegames.common.sfs.social.user...

I have a web application and a smartfoxserver running in the save machine. And the web application is used as a monitor. Every minute, it would simulate a client to connect to smartfox server, log in a zone, handle a custom event and disconnect. Every step would be logged. Normally the log is 9 Jun ...

Extension queue is not continuously busy. I saw quick burst of queue activity once (more than thousands), but usually the queue size is below 5.
I didn't see special server side logs.
I do use database to check the login credentials.

Here is the code in login handler. We use user id in our system as user name in Smartfoxserver, so it is long instead of String. There is DB check to see if user exists. public void handleServerEvent(ISFSEvent event) throws SFSException { try{ Session session = (Session) event.getParameter(SFSEventP...

If so keep an eye on the server queues status via the AdminTool > Dashboard, it's likely you will find some anomalies in the Extension queue. If so let us know. Is there a way to save queues status into file? The issue did not happen all the time. When i take a look at my monitor data and found the...

I am not sure how did you determine these two threads are those with the highest cpu time. Did you compare the PIDs? Yes. 7719 -> nid=0x1e27 7707 -> nid=0x1e1b I would recommend checking via the AminTool Dashboard and monitor if those thread are staying at the top of the list for long times or it i...
