Issue/Introduction
A Uproc within a session ran twice with two different launch numbers almost consecutive and the same session number which should never occur.
We can't see anything wrong and it seems something similar happened few weeks ago.
We checked the activity logging and could not find any user manually launching the job neither in the logs of the node.
Nevertheless, a Uproc from the same session number was indeed first Held and then released several minutes before the issue occurred.
Environment
Release : 6.x and 7.x
Component: Dollar Universe
Cause
Product Limitation
Resolution
Product Management and Engineering feedaback:
The result is that the issue may occur due to an internal mechanism between the Launcher and the Calculator. This behavior is random and appears on the breakpoint between two consecutive outages.
The problem is linked to the way outages are managed between the Calculator and the Launcher, and solving it means completely rewriting the outage functionality, which we may consider as par of a RFE (Request for Enhancement).
A simple and recommended workaround exists: create a single outage covering the whole maintenance period and delete it when necessary. A fix was provided for this since version 6.10.01. so make sure to be on a version equal or superior.
