Hi

We have a customer running K2.Net 2003.
The last couple of days we have been experiencing errors in K2 like the following:

"Item has already been added. Key in dictionary: '760'  Key being added: '760'"

Appearantly this is a known issue and we have located a hotfix here: (Hotfix 2)
https://portal.k2workflow.com/downloads/sets/hotfixDetail.aspx?id=12

The K2 Server has been running for a while without us ever seeing this error before.
So my question is really how these errors now suddenly appear.

 Any thoughts would be appreciated
