Which Kartris version are you using? It looks like the issue is something that is set to be a tinyint (max size 255) is being set to more than that. I recall we have changed one or two tinyint values to small int or int over the past few years, so that would seem to be the first place to start if we know which version it is.

I have 28002 installed on ISS7.5 (WinSvr2008R2 & SQL2008R2)
I tracked this down to the SP that specified an input variable as a tinyint, I changed the input variable declaration to int and then ran the website again, the problem didn't recur but I wasn't happy the leave it at that. I checked the field data-type that the SP was referencing and it was tinyint, so the problem shouldnt have been fixed by changing variable declaration in the SP.
I changed the SP back to its original state and the problem has not returned.
I did not have the luxury of time and so didn't get the opportunity to track this problem to its root cause therefore I have to expect the problem to recur at some point.What makes things worse is that I'm not even sure which user actions led to the problem.

I think in all likelihood, the change you did fixed the problem, but the sproc is used by a control on the site whose output is cached. Therefore, after the fix, it runs, and the control does what it should, and then gets cached. You revert the sproc, but because the control has cached a good copy, it doesn't re-run the sproc again.
But the cache would eventually expire and the problem would be back. So I would not change the sproc back to the original version, I would keep the change you made which seemed to fix the problem.
