Dear All ,

I have a major issue in my workflow in production client . In SWEL there are some workflows which

got started & then error occured as per the message " A system error has occured in lock management " and no workitem gets created .

This issue happened just 1 day back and still continues somtimes .

If any one have any idea on the issue , what is the root cause of the issue , please suggest how to solve the same .
