Error while enabling the execution of Process

While enabling the execution of Process in MywebMethods,

webMethods Configuration -> Process Configuration -> Business Process -> <Process_Name> -> “Execution Enabled”

I am getting an error in server log. Have you come across this anytime? If so, kindly let me know what is the remedy.
