Error description

  • Client create a remote server in RAD pointing to remote WAS
v8.0.0.4 z/os server, the remote server can be connected without
problem, and project can be published to remote server
successfully.

But client find that immediately after RAD connect to WAS z/os,
CPU utilization for the ASRA address space  increases
considerably,  to 15% of ZIIP/ZAPP on Z114/2818 M05.

WAS team analyzed client's ZOS dump file and log file, they
suspect that the high CPU utilization might be caused by RAD
always try to download try to download from


'/u/wasv8config/h1basea/h1nodea/AppServer/profiles/default/confi
g/temp/logs/sysout'

But always get file does not exist error, this increase CPU
utilisation.
