When displaying a job output from a z/OSMF workflow, the following message is received:
IZUG856E z/OSMF cannot confirm that the request completed because the server did not respond in the time allotted. Refresh the page, or try the request again.
z/OSMF is not managing to deal with large job outputs and the message IZUG856E is issued as a result.
The APAR PH48070 was published by IBM to correct this problem.
