<<It’s been a while since I gave na update on my situation here.

To recap, firebird 3 is crashing randomly on my server. It may crash once, twice, or 10 times a day. Or not once during the day.
Server load is always minimal during the crashes, and so is the memory usage.
With the help of the community, my latest attempts where to change the firebird.conf, and I tried a lot of different combinations, even returning to the default combination, but the problem still happens.

Then, I tried to capture the crash dumps.
I followed the instructions at Collecting User-Mode Dumps:
https://msdn.microsoft.com/en-us/library/windows/desktop/bb787181.aspx
However, I’ve had a lot of crashes since I changed the registry, but no crash dumps are collected at all.
I’ve made sure the dump directory is writable and readable by everyone (system, admin, user, etc).
I also turned off the guardian as required, and created a simple batch file to restart firebird every 5 seconds if needed to act as a guardian.


Before turning off the guardian, firebird.log always wrote a terminated abnormally (4294967295) error, not without the guardian it doesn’t write anything at all, it just crashes silently.

So this is the status now.
I’m thinking on trying to install de debug version and attach Watson to it, if anyone have any other ideas I’d be glad to hear.>>

Try following these instructions....
