What I am doing is that I am using a programme that tries to access a certain table within an oracle database (on a server), and the error is very specific:
The program is for entering drilling (oilwells) data into the db and enters data in the following order:
Well->event->report->Day, and this error message only happens for one specific well, one spesific event, one spesific report on two spesific days. This error does not occur on any other days.
