OK I'm not out of the woods here :(
All that killing the anti-virus crap has done is allowed the machine to run a
lot faster, so that a restart is completed faster. While this is only
happening three or four times a day, it's making IBObjects unusable with Linux
servers. I've had to switch back to Windows for next week to keep the customer
happy, but the path forward means that I MUST sort this out.

Even the extra logging added to the BCB6 program has not been fired when the
program closes. There is nothing in the Firebird log that reliably corresponds
with the crash. Everything I throw at the program to try and create the
problem simply gives a 'clean' error report. The same program is running on a
number of windows powered sites without any problem, and I expect to see no
restarts in the coming week. It's only one of the programs connected to
Firebird at the time and the others carry on fine - restarting the failed
program when it is found to have stopped on the next minute. While I can
modify checking to ensure a faster restart after a crash, the ticket printer
then throws out a '9999' test ticket which it would be difficult to prevent.

ANY ideas what I can try next ????
Jason please - what on the database connection side could cause an immediate
