When we try to kill a job the operation fails and the following message is returned:
CAUAJM_I_40245 EVENT: KILLJOB JOB: job12
CAUAJM_W_40032 A KILLJOB or SENDSIG operation is already in progress for job <job12>. Request ignored.
The recommended solution is to set the job status to TERMINATED by using the following command:
sendevent -E CHANGE_STATUS -s TERMINATED -J jobname
Problem was resolved by applying this solution.
