Something that server does not like. You might want to check Firebird
sources to know exact reason - first you have to find symbolic defintion for
error code 65, then you can look for that particular error. :) Or to try to
ask in firebird-devel list...

There is no chance to learn about this error more except reading the
sources. This error comes from Firebird itself when we tries to start the
Services API operation. This part of the API is not very good documented
compared to other parts. If you can reproduce it only by starting two backup
processes for the same database, then workaround is very simple - don't do
it... If that is something different, we have to try to find the reason with
firebird-devel together.
