in Backend Log of my MARS I find literally hundreds of messages as follows:
7/24/08 4:50:26 PM CEST Error ./device_monitor Thread 41372592:Device monitor trying to add entry with interfaceId = 0 to pn_report_result table. Skipping.
Any suggestions how I can identify the device which causes this error?
Actually it seems you are hitting another bug :)
