    "Could not create an index searcher with the supplied lucene directory"

    Using Umbraco 7

    Every couple of days or so, we see about 30 seconds of this error in our logs, and it disappears on its own, however users receive our Custom 500 page while this error is occurring.  Everything I could find on resolving this error usually involves removing files in the TEMP/ExamineIndexes subfolders, but we have done that and the problem resurfaced within a week.  We do not deploy that folder at all, so that shouldn't be an issue in our case.  A little background on our environment:

    • Azure Website (Basic plan, Medium Instance, Single Instance)
    • Auto-deployed from Github "PRODUCTION" branch
    • Umbraco 7.2.1
    • Error seems to be initially triggered by a call to UmbracoHelper.Media() in every instance I've seen in the logs so far, so it seems to me there is a background process running that is locking the index files for reading by the front-end.
    Anyone know possible causes for this error?  Any ideas as to how we can prevent this error in the future?  Stack example:
