JDBC and the BDE

Our web application queries the Paradox tables through JDBC every 30 minutes to update our local copy of the data. This scheduled query will run
for about a day and a half before it starts failing with this error:

Error message: Error while trying to connect to database, Exception message:
While trying to obtain Connection object, there was a ProviderFailure exception on the server.
Following are BDE Error messages:
BDE ERROR CODE: 9488 MESSAGE: Too many sessions.

We are closing all connections and database resources after the update is finished. For
some reason, the server is running out of resources.

Is increasing the number of sessions in APPSRV~1.pro from the default 45 to a higher number the right direction to address this issue?
