    We have an Umbraco 6.1.6 site with about 8000 nodes most of which utilize uHidesy.

    Intermittently when attempting to load a content node an editor will be presented with this error. Any thoughts?

    Here's a slightly different one that shows up as well:

    You're not on a SAN are you?

    Yes. We're running on a virtual server with a SAN. It's running on the high-performance disk groups.

    If you're on distributed servers, there may be a file locking issue with yoru load balancing.

    We're currently not doing any load balancing. The error seems to only appear when there's a significant number of editors working. How would you go about preventing file locking?

    Ah. I'm not sure about this file locking issue. The datatype just reads and writes to the file. Perhaps what you could do is add an if statement to the source which checks if a User is an admin. If they are then just return. That will mean the file will not be locked by writes.

    Hmm...Interesting. I'll give that a shot.
