HPS5103 The data source connection has been removed, probably because the maxBusyTime has expired

Explanation
The connection to the host application or database has already
been removed. It is possible that maxBusyTime has been configured
in the .poolspec file for this application and time has expired, causing
the connection  to be terminated before the Integration Object returned
the connection. This can occur when an application with chained Integration
Objects is running, and the end user pauses between two middle-in-chain
Integration Objects for a time longer than the maxBusyTime configured
for the connection pool.

User response
Ensure that maxBusyTime is set to an appropriate value. In Host
Access,  click the Connection
Pools tab in the left pane. In the right pane, click the Connection Pool Configuration tab,
then in the Connection Timeouts box,
type a new value for Maximum busy time before disconnection.
