CBR6421I OAM experienced an error moving data from address space ASID=asid to the OAM address space.
Explanation
OAM executed an MVCP (move character to primary) instruction to retrieve data from a user address space and move the data into a buffer in the OAM address space. The data movement failed. It is likely the user address space is no longer active.
System action
OAM stops trying to cross-memory-copy information from the address space asid which encountered the error.
Operator response
Notify the system programmer.
System programmer response
Investigate the state of address space asid. It is possible that address space abnormally terminated for some reason which is unrelated to OAM processing.
