Maintenance Order Settlement - "MC603 Lock Table Overflow" Error

Hello , I am running RKO7KO8G- "Settlement of Maintenance Orders" program in background. For few Orders I am getting "MC603:Lock Table overflow " error. What might be the problem for this.

Number of Order processed in a job is around 10,000.

I checked in SM12 table.No entry is found.

Size of the Lock table details is

Min - 4096

Max - 102400

Diff Value - 4096

Profile Value - 10000

Current Value - 10000
