After a CPU hotplug event, the record size for the running operating
system data collection is no longer correct. The appldata_os module tried
to start a new data collection with the correct record size but received
an error from the z/VM diagnose call DIAG 0xDC. Any data collected with
the current record size might be faulty.
User response
Start a new data collection with the cappldata_os module. For information
about starting data collections see "Device Drivers, Features, and
Commands". For information about the return codes see the section about
DIAGNOSE Code X'DC' in "z/VM CP Programming Services".
