I am using following "sortintegerarray" function in my process but sometime this function is not working and i am getting following error.

There is a problem with task “Script Task” in the process XXXXXXX. The expression function 'sortintegerarray({1000000},0)' (user=xxxxx, exprId=500000) could not be evaluated: The passed parameter(s) are incorrect, or the function 'sortintegerarray' may be unavailable. (Data Outputs)

But when i manually start the node it is working fine. Have any one faced same problem.
