Hi,
when I tried to run my DS Sequencer through the script, the sequencer is Aborted with the following message.

main_program: The section leader on bdwux407_udb1.service.com died

Plz clarify what this message is ?

A parallel job is like an orchestra. There is one conductor process exerting overall control. On each processing node there is a section leader process exerting control over all the player processes (one per stage, unless combined) on that processing node.

For some reason, the section leader process on the indicated node has died (either aborted - in which case resetting the job may bring more diagnostic information into the job log) or "someone" has killed the process.

Under what circumstances this section leader process can die?

suppose if i run a job that process millions of records, can it cause
section leader process to death. so that if others also tried to run there jobs, it will also get aborted.

If number of process increased which may exceed the capacity of the section leader for that particular time to handle or may be even if communicaiton between the conductor and Section leader fails.

The whole point of PX is to process huge volumes. It is usually some external event, such as a kill command, that kills DataStage process. If it is an internal event, you may see a core file where that process executes.
