Unexpted error when accessing pictures on publishing web. From the ULS log it looks like this is BLOB cache related. The following error message is found for the correlation id:

Any ideas?

Reset to default

That method will throw an ArgumentOutOfRangeException if the date passed into it is in the future. This would appear to be the last modified date on one of the pictures held in the library.

I'd try the following:

  1. Ensure that all the last modified times on the files in the library are sensible
  2. Clear out the blob cache

(Also wondering if you might have some servers in your farm with out of sync clocks?)

    One of the servers were 14 secs out of sync with the others. This was also the server that had the error, so I will mark this as the answer.
