We just had a production lpar lockup due to a SPIN LOOP.
With the dumps taken it appears to be waiting for CA PDSMAN.
After an upgrade of the operating system a spin loop seemed to occur and it was waiting on CA PDSMAN SVCs.
The appearance that CA PDSMAN was the cause is not accurate. IBM discovered the rel problem and it was resolved by the following :
IBM PTF UA93670
