Re: delayed room variables update after creation of a new room

A follow-up question: Where and how to set this global flag? On the server side only. You can create a Room Variable from server side and set the isGlobal flag. We don't provide this from client side because it can be easily abused to overload the server, as global variables generate a larger amoun...

Re: about extension reload

I think is not class name or similar issues, Is it possible that the class loader is releasing unused classes prematurely? No, there is no such thing. The class loader is supposed to load classes as they are encountered for the first time. The stack trace you have posted shows that the missing clas...

Re: About Extension Reloads

Hi,
2.update something causes a 'java.lang.NoClassDefFoundError'(unload fail) ,

Check the name of the class that causes the exception and verify that the relative jar file (containing such class) is deployed correctly.

Cheers

Re: delayed room variables update after creation of a new room

I see. I combined the CreateRoomRequest with the autoJoin option but listened only on the ROOM_ADD event. Could it be that, in addition, I should wait on the ROOM_JOIN event? It depends on what your client logic needs to do. If you need to access RoomVariables then you will need ROOM_JOIN, otherwis...

Re: delayed room variables update after creation of a new room

One small addition... RoomVars that have the "global" flag turned on can be accessed from Users not joined in the Room.

Re: High RAM usage when using SmartFox

Hi, SmartFoxServer doesn't need much memory to operate even with 1000s of concurrent players. The server will allocate more memory if necessary, otherwise il will use just what is needed.

Re: Same machine spec but got different initial max mem heap usage

Hello, without custom memory settings the Java Virtual Machine (JVM) will allocate the heap size dynamically. You can read more on how this works here, for example: https://stackoverflow.com/questions/4667483/how-is-the-default-max-java-heap-size-determined I wouldn't worry too much about this as th...

Re: Thread keep increasing and Sudden Jump in heap memory

Hi, the graph you have posted for the NPC manager shows a normal memory activity for the time interval measured. There is no evidence of an increasing usage of RAM in the diagram. The situation seems the same for thread count, which is quite high, but it's a flat line from start to finish. So I am n...

Re: High RAM usage when using SmartFox

Hi,
normally SFS2X does not require that much RAM but depending on the amount of traffic and custom server side code you're using it can eat up more resource. Did you change the default memory settings of the server?
If so how?

Thanks

Re: sfs2x-service restart

Hi, we have no idea, maybe there's some activity still going on in SFS2X that is using the database? You can actually assess that by monitoring the MySQL server before restarting. If you restart the DB while queries are being sent to it, it is very likely that after the restart queries will keep com...

Re: Socket Exceptions

Hi,
these exceptions are not particularly significant. They happen when data in the outgoing queue is being written but, concurrently, the client connection was shut down. It's expected to see some of these error in any live server.

Re: Tomcat upgrade

Hi,
we plan to include a Tomcat upgrade in the next SFS2X release 2.20 but we don't have a release date set for now.
I will likely post an update in the next few weeks.

Re: configuration for comment bitswarm.sessions.DefaultSessionManager logs

It's not clear if this is something that has happened a few times or if it's constantly happening. It is possible that external servers are scanning an IP range and trying to connect to anything that they find, maybe searching for a vulnerable machine or something like that. Personally I find it odd...
