DU: XA Lines not correctly purged from u_fmev60 in HDP remote conditions

CA Automic Dollar Universe


The u_fmev60.dta file from a Central Node that submits many jobs via Sessions containing HDP towards remote nodes contains a lot of XA lines regarding these HDP sessions.

This provokes the Launcher to slowly reduce its performances impacting the Job Submissions.

The expected behavior would be that the number of XA lines that are contained on the u_fmev60.dta file is equal to the total number of Local or Remote Uprocs that are waiting for a Job Event.

As soon as the Job Event matches the expected Status, the XA line should be removed on both the central and the execution node. On this case, it would only be deleted from the execution node.


Incorrect purge of XA lines from u_fmev60.dta in central node in case of HDP dependencies.
