Hi,

I send a lot commands but never get this kind of issue.

What version of SFS2X are you running?
If possible I'd recommend updating to 2.17.3 which fixes a potential issue related to this.
https://www.smartfoxserver.com/download/#p=updates

Also, please, check that this error is not happening when sending data to clients in a Scheduled Task. If it is this is likely caused by canceling the task abruptly instead of letting it finish it's current job.

Cheers

What version of SFS2X are you running?

I am using SFS 2.17.0

Also, please, check that this error is not happening when sending data to clients in a Scheduled Task. If it is this is likely caused by canceling the task abruptly instead of letting it finish it's current job.

How can I verify this? This is problem in one command only

Note:

It is not coming for all users in the room.

Hi,

I am not sure what you mean. What command are you referring to?

As regards the Scheduled Task I was mentioning. If you are using them, make sure that when you call the Task.cancel() method you don't use the this version of the command:

Code: Select all

Task.cancel(true);

Here the extra boolean tells the Task to shutdown immediately regardless of what the current thread executing it is doing. This can cause the kind of error you have reported. If you have similar code in your Extension just remove the true parameter, so that the Task has a chance to complete its job before being removed from the Scheduler.

Cheers

Hi;
I updated smartfox server 2.17.3 from 2.12.0. Same problem was occurred on WebGL clients (not Android or IOS). I fixed problem with Lapo answer. If you use "Task.cancel(true);" on your game or zone extension codes , change it to "Task.cancel(false);"

Thank you for answer , Lapo.

Thank you for answer , Lapo.

Sure, no problem
