Message number: 751
Message text: Timeout during logon to server
The gateway has sent a login to the application server. This process was
taking too long and was therefore cancelled. The time period is defined
by parameter gw/accept_timeout.
There are two reasons for this error:
The application server has rejected the request (internal error)
All work processes were busy and the request could not be processed in
the given time. In this case, error CONV_ID_NOT_FOUND is returned to the
server since the gateway has already deleted this connection.
The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
