3 Days later it happened again
1) Changed Host Settings to NO CACHE

UPDATE: It hasnt happend for 2 weeks now!!

I will post back here if it happens again and or I figure out the solution. Time will tell.

OK it happened again even with NO CACHE but it took half a month this time at least. Also when it did it was when the application had shutdown and restarted itself.

-just giving an update since I said I would.

Has anyone found a solution to this issue. We're running 4.8.2 and the issue listed is affecting us. The site is fairly busy (400 users daily, and about 70,000 hits). There is only one portal in this installation. It's not prudent for us to disable caching, which appearntly doesn't help (much.)

 

Any suggestions?

Me too now - a 4.82 site with no previous problems of this sort.

It happened after an app restart and took two recycle kicks to get the site back.

Probably a coincidence but this started to happen after a I dropped a google analytics module on a few pages ?

This may fly in the face of every thing holly but I am trying out a theory.. I am turning off Application Pool Recycling.  The reason is, I see problems tend to happen after a recycle. 

I will report back any updates.

This issue has been around since January, does anyone have a resolution yet? Please post here if you have this issue, we need to get this thread looked at I don't believe anyone is taking it seriously.

I get this error on lots of different pages and it slows my server, I have had it for 3 versions now.
