Progress OpenEdge 10.2B / QlikSense (ODBC-Problem)

[#1]

The connect (via ODBC) - between Progress & Qlik - works.

But after a period of time I lost the connection to the Progress-Database.

I find errors (in the Progress-DB-Log) like:

- Broker detects death of server.

- Disconnecting dead server x.

Could anyone help?

Regards

Stefan
