Hi, thanks for posting.
First, I would suggest that you download and install the 2.5.1 VMmark patch. It is very fast and easy to install, just follow the instructions in ReadMe.txt.
From looking at your files, the message Could not Run the following 4 Wklds: ['MailServer0 reported issues during run', 'DS2WebBServer Tile0 failed to start/complete process', 'OlioWebServer Tile0 failed to start/complete process', 'DS2WebAServer Tile0 failed to start/complete process'] is occurring because the Mailserver0, Olio and DS2 workloads are not functioning correctly at this point. I'll get back to you when I have more information. You may look for error messages in the .wrf files, and then look for those errors in the Troubleshooting section of the VMmark Benchmarking Guide, or search this forum for those errors.
Thanks,
Rebecca
