Hi,
Recently installed SharePoint 2013 and the search component has been running fine for the last week for so. A few hours after a schedule reboot, we started seeing some errors that SP is unable to parse contents. No changes has been made on the farm and wondering if anyone else has experience a similar issue?
After seeing the below error message, SP search is broken (unable to return search result) and is unable to crawl contents (docx, xlsx and pdf).
Error message:
Processing this item failed because of an unknown error when trying to parse its contents. ( Error parsing document 'https://url.com/test2.pdf'. Sandbox worker pool is closed.; SearchID = 356C78C7-4317-4528-87C6-303D86FB74DC )
Any help is greatly appreciated.
