Hi All, just a FYI
I installed SP 15 the other day and ended up with failures on 5 servers the next back-up cycle. error code 17:72 failed to process failed items from index. Contacted support and was told it is a known issue and will be fixed via a HF. Support sent me this link - works the charm in the meantime.
Article ID: 53361 - ERROR CODE [17:72]: Failed to process failed items from index
Hotfix 2308 fixes the issue or deleting the 'failures.cvf' file in the Job Results folder on the client will work around the issue.
