Hi Helen,
Thanks for your suggestions, I have collected dumps of FBServer.exe while
it crashed, doin some initial analysis I found that the bug check is related to
access violation.
Any idea on how do I proceed with resolving this issue?

The first step would be to inspect the firebird.log and see whether anything
was going on prior to the crash. Of course you won't see anything if this
"crash" wasn't a crash but someone rebooting the server or stopping the
service. (Cleaning staff coming in at roughly the same time every day and
pulling out the server plug so they can plug in their vacuum cleaner? Not a
joke - it really happens!)
Another thing that can cause Firebird to crash is a bad UDF. That won't usually
cause a log message because it may have crashed the server before it had a
chance to generate one.
You might like to have a look at the Bug Fixes section of the Firebird 2.5.4
release notes, under "Server crashes" in case something there rings a bell. You
can read them on-line:
http://www.firebirdsql.org/file/documentation/release_notes/html/rlsnotes254.html#bug-254-crashes
Or you might simply want to do the easy thing and replace your installation
with v.2.5.4.
Helen
