Thanks for the response. Yes, that is what i did to force a recrawl. It was about 24 to 48 hours after that, I had the cache issue. Seemed like a possible correlation of G actively or very recently crawling and the G 404 page returning during that time.
Was wondering if anyone else had noticed that as well or if it was just a coincidence.
Thx again for your response and cheers!
