Any suggestions on how to fix it? I just tried to reproduce this with my modification above and aborted on i=700 without any problems: swupdate as well as client are still running fine. I also tried to install several times with the same client command, also no problems. Can you elaborate a bit more on your setup? Kind regards, Christian
