Hi,

I encountered this error when one of my workflow runs. This always happens at the very first activity in the workflow. The puzzling thing is it only happens once in a while and once we redeploy the solution (with no changes made), it will be fine. Does anybody encounter similar experience before?

Sorry that at this point, this is all I can see from the error logs in K2 management console. I have custom logs written (log4net) but then it can't even log the first statement in that activity. So my logs are blank.
