Processor,<no principal>,Alarm Push Processor, Reading alarms from http://localhost:80/EcoStruxure/DataExchange with no last update

Hi,

We have a SmartConnector extension that pushes alarms from the EBO to our system. The processor running using a 2-3 seconds scheduler. In most cases it runs OK, and when running you can see this line in the SmartConnector log file:

Debug, Processor,<no principal>,Alarm Push Processor, Reading alarms from http://localhost:80/EcoStruxure/DataExchange with last update: b45c427b-c3b5-4405-bd95-c1bb1188257a|10998674,

From time to time, we see this errors:

Starting the error above, all calls returns without last update. See below.

See the attached SmartConnector log file.

Any idea what is causing this error?

Thanks.
