i'm having an issue with my Mango installation. We are using ver Mango 2.0.6 against a Derby db, java jdk is 1.7.0_21 and using serial RXTX libs for serial communication. We recently updated our server that hosts the Mango install running all required Windows updates (Windows Server 2008 R2 Enterprise OS) and since then, we have had an issue every time we try to update Data Point data. Right now it looks like it is happening specifically when we try to change the data period and save --> we get an error message that the Data Source has stopped and then Mango stops/crashes.
It takes us 3 hours to restart/re-init the system so these errors need to be fixed asap. Any ideas?
here's a bit of the error that is dumped to text file:

I have confirmed all dlls and paths for java. any idea of why this could be happening? Any help/insight would be greatly appreciated.
