Could you please try to paste (or email) logs from a debug = true client where its possible to see the data sent/received by the client.
Usually in player.log
We also need a small repro test case - as small as possible. That will expedite finding the issue
Best

We are on RC3 now and no change in this issue for us. Clients still get into a state where they stop responding or receiving messages from the server after one of these errors shows up in the log.

Hi,
I get pretty similar errors with the latest RC3 Java Client API (but used to happen in all the other versions before as well). I am basically trying to run a load test via the Java Client API to monitor server load etc. But everything above roughly 50 users starts throwing the below errors. The behaviour is pretty random. Though from my last runs most of the errors seem to appear after a room join. After that the client hangs in the same indefinite state and does not report any events or respond.
Some of the errors only turn up as:
Code: Select all
[BitSwarmClient] - ## SocketDataError: Data format exception decompressing bufferSome are:

I have also tried changing the compression settings without any change. The errors keep coming randomly.

Few users have posted similar errors. We are working closely with customers who have reported issues like these.
As of today we are practically 100% confident that there's no issue with the Server and this problem is caused by a network error.
Should this problem persist or affect a large number of clients you should check your bandwidth and overall quality of the server side network infrastructure.

Hello,
We have the same problem with invalid SFSDataType(Expected: SFS_OBJECT). Is there any solution for that issue already?
In our case it starts when 4-5 users are connected. More users join faster it comes. In fact users receive this error not simultaneously but one by one in the range of 30 seconds or so. We have the latest versions of sfs2x server and client API (Unity C#).
Thanks for help beforehand,

Do you have a way to reproduce it? If so please get in touch with us via email and we'll exchange the necessary files to study the case.
Make sure that you're running RC3 and the latest C#Â API available.

This is annoying. We have revamped the java code, used the latest patch, optimized the objects being sent and received, controlled how may packets are being sent / second and also used UDP for positional updates. We have been battling this for months with no positive result. I started this post in May last year and this error is still prevalent. Any hopes on addressing this? Is there a solution? What is causing this? Can you atleast list out the reasons why this could happen? We have invested a lot of time and effort out here and we would appreciate some direction on this matter. Thanks.

Just to understand. Are you using SFS2X 2.0.1 and the client API provided with it?
If so, can you please give me access to your application so that I can login and see the problem in action?
thanks

Yes its SFS 2x and the latest client API. I shall setup something for you in some time.

Usually this kind of error is only seen if there's a network error. In that case invalid data may arrive at the client and generate an error, after which the connection might be lost or unresponsive (client side).
If you think this is a different scenario then please provide more context, including all possibile details and a description on how this error is triggered or the steps by which the problem can be replicated.
Thanks
