Error- Network: Frames larger than MTU

Hi all;

I have the last months this error: Error- Network: Frames larger than MTU

I used JDE Applicacion installed in the CITRIX enviroment.

The archictecture is JDE--> CITRIX  -> HP (Data Base)

We saw the citrix server was to sent package larger than MTU, established in HP server.

I need validate these:

Can be fragment the package sent the CITRIX ?

Is possible made that JDE application can be fragment the package, becuase this situation generated disconnection of the application

Thanks

Regards.
