    W3 Total Cache has been working well for us but we have noticed this recurring error. I couldn’t find anyone discussing the error here or on Google search but I did find a lot of other sites indexed by Google using the search keywords: “w3” “stat failed” and “line 159.”

    We sometimes receive these errors three or more times a minute, at least once an hour. Here’s a sample:

    Please let us know if this indicates some problem in our configuration, or perhaps even, an issue with another plugin — and thank you!

    Hello @spaceling

    Thank you for reaching out and I am happy to help!
    Just to confirm, you are using Object Caching and caching do disk? It’s not recommended to use Object Caching when the only available caching method is Disk. I would recommend installing php Redis or php memcached extensions if you are planning to use Object Caching. The reason for this is a potentially large number of OC files that may be cached to disk and some servers have problems dealing with those.

    Thanks!
