I am using FB 1.5 with Red Hat 9.0 and I noticed that the work
stations lose the connection if they are a certain time idlers,
returning the following message when trying to enter in any routine
of the application:

ISC ERROR MESSAGE: CODE 335544721

ISC ERROR MESSAGE

UNABLE TO COMPLETES NETWORK REQUEST TO HOST
ERROR READING DATES FROM THE CONNECTION
AN ESTABLISHED CONNECTION WAS ANNULLED BY THE SOFTWARE IN THE
COMPUTADOR HOST

Would anybody know informs me the solution for this problem?

Thankful.
