Our client is receiving an intermittent issue (every month or so) whereby the Excel Services cache inside
C:\Windows\Temp\Excel Server\FileCache\GUID\ will having missing sub directories.
When Excel Services is running, it should have directories for:
On occasion, one or more of these directories are missing, causing Excel Services based reports to be failing:
Unable to create or access workbook cache at C:\Windows\TEMP\Excel Server\FileCache\0b0faa2c-0612-4045-a910-8a9c2a794cf1\Ranges. Excel Services Application is unable to function without a workbook cache
When this happens I need to manually recreate the directories and the service works again. However, the issue seems to recur every month or so.
When I restart the Excel Services on the affected machine, it is able to create the directories itself, so I know it's not a permissions issue with the service account. In addition, the HD has plenty of space left so I don't think it's a disk space issue either.
Thanks in advance for any possible insights into the issue.
