Have you gotten it today? I changed server settings last night on how PHP was processed and it has dropped the server load by quite a bit. As of right now the server load is .36, and should indicate there is basically no load on it and all pages should be getting served promptly.
Thanks!
PS the setting you are referring to would make the error go away, but a huge delay would take its place... so really doesn't solve the issue.
None so far today, but the pattern I experienced was that several days or even up to a week would pass before I got the message again.
Yes, better to have the message.
