Please try to compose a small sample reproducing the error and send it to andreyz*devart*com .

My problem (and beleive me) is that I'm not able to find a pattern to reproduce it.
I've a software connected 24 hours per days to an industrial hardware, collecting data and storing it into an postgresql databse. From time to time (that's to much for my pseudo real time software) I'm getting these exceptions...

Don't you have a debug unit that I can use instead ?

UniDAC has no functionality for logging. You can add logging in your application by yourself, in order to localize the error occurrence and then stably reproduce it. To investigate the problem, we need steps to reproduce it or a sample demonstrating it.
