We have a sequence job that sends an email using the "NotificationActivity" stage. This is a parameterized job, so it is executed 6 times with different parameters. (Jobs are set to allow multiple instances.)
(I've removed some of the actual path names)

processPLASOfficeUpdates.processPLASRDServiceCenterOfficeUpdates.JobControl (DSSendMail): Error when executing command: /etl/Ascential/DataStage/Projects/.../sendmail_processPLASOfficeUpdates.sh
*** Output from command was: ***
/etl/Ascential/DataStage/Projects/.../sendmail_processPLASOfficeUpdates.sh: /etl/Ascential/DataStage/Projects/.../sendmail_processPLASOfficeUpdates.sh: cannot open

This email step was executed successfully five times, but one of the times it errored out. Is there any question of contention between the jobs? What else could cause the error?

you can check whether you have proper permissions to rwx to it.
