Why would he need to use the native driver instead of the pure-java driver?
That advice doesn't really make sense without giving actual arguments for
doing that. I do hope you are aware that the Firebird protocol has
versioning, and continues to support previous versions of the protocol.
Having said that, trying native instead of pure-jave might be a good
troubleshooting step.

Most likely the same error would occur with the native driver as this seems
to be a network transport error, which might be a result of a trigger happy
firewall, bad network cables etc. BTW: You might also want to check with
Redsoft, as I assume - based on the database location - that you are using
Red Database (based on Firebird) instead of Firebird itself.
