Hi John,

The log is very clear. There is evidently a big issue with your Data Adapter.

I see that the total threads are between 5800-6500. Consider that Lightstreamer Server in your case creates less than 400 threads (I guess your machine has 64 cores, right?). This means that your Data Adapter creates more than 6000 threads!

You might want to issue a thread dump to see the identity of all those threads and demonstrate the problem with the Adapter.

I also see huge memory consumption: roughly 8 GB used by the JVM, where only 450 MB are used by the Java heap. So it seems that your Data Adapter creates a lot of thread and consumes a lot of memory (apparently out of heap memory).

Furthermore, all the indicators of Lightstreamer Server performance are great. There are no queued events, the thread pools are completely idle, no delays are reported.

From a general perspective, I confirm that the traffic is so light that a monster machine like the one you are using should probably handle millions of users, not hundreds...

I hope that helps in nailing down your issue.

Cheers,
Alessandro
