Before you get too involved with analysing network traffic, 
check that this isn't simply InterBase working as designed/

I've never used InterBase, but I used to work with an Oracle 
application and the Oracle SQL server would sever any idle 
connections after some (configurable) amount of time; this
was touted as for security, but I suspect that it was mainly 
a way of closing connections for workstations that had crashed/
been turned off/ whatever.  Our application had a "Lock" screen
which closed the connection and re-opened it when the user 
supplied their password, which people were encouraged to use to 
avoid being cut off without notice.
