<![CDATA[Crashing when polling rate too high from OPC UA client.]]>When the OPC UA client (Kepware) is polling the OPC UA server then the rexcore is crashing and there is no more communication possible anymore. (even downloading a new program or diagnostics isn't possible)

It seems that it causes the rexcore to crash when the polling frequency is too high.

I am not in control of the PC that is running this Keptware software.

I believe that it was originally set at 1Hz but I am not sure, but when it was set to 0,1Hz it was working fine.
For the moment it is still crashing the application because I believe it is set at a too high polling rate again. (I assume....I am not in control and do have no access on this PC, so it's hard to verify if this is the real problem.)
But if I change the port number of the OPC UA server to make sure nobody is polling the server then everything keeps running fine.

It would be good that only the communication would stop and not the entire rexcore.

I will send you a PM with the complete setup.

thanks for this bug report. Please, what is the approx. polling frequency? How many items are you reading?

Cheers,
Tomas
