I have an issue with our system. The reloads keep failing (different tasks not always the same and different data sources) - the crash created a core dump file. I have had a look at it with Visual studio but it doesn't really say anyuthing - also had a look at it with notepad and I could see a lot of stuff which are not in Visual Studio.
Coud you recommend me a tool what to use to analyze this dump file ?
Connections to databases are mainly done via ODBC or OLEDB which is the database connection layer in Windows. For every specific database vendor there is a database driver - which in your case seems to be PostgreSQL. The core dumps you are getting might indicate that it is a problem with your database driver.
Even though you are connecting to different databases they might be hosted on the same vendor database - thus using the same database driver. It might be worth looking into which version of the driver you are using and see if there are newer versions available that might fix your issues.
The symptoms you are seeing indicates that this is the place to look...
