I have created few crystal reports (2013 version designer). Reports are called directly from menu. It works OK, but after some time I get an error seen in the picture. Solution is very easy, just recycle application pool and it is just fine again. This seems to me like a bug and it is very difficult to live with it for the client.
Any advice or workaround?
Do all the reports stop working after the first appearance of this error? Or only this specific report stops working?
All the reports without exeption. After recycling all of them are OK again.
Try the latest service pack from SAP http://update.simplicor.com/asap/release/win32/CRRuntime_12_7_mlb.exe
Thank you, I reinstalled CR runtime and it seems to work just fine so far, even without recycling.
Well, so upgrading of CR runtime did not solve the situation. It is happening again. I watched it for some time and there is no concrete interval after restart when it is malfunctional. The only solution is regular recycling which is very ackward as user have to renew their browser every time after recycling is done.

We could not find the reason so far. How many reports a day do you run approximately?
