Patch level detected:Dollar Universe 6.0.00
Product Version: Dollar.Universe 6.0.0

Description :Under heavy load, when launching jobs to a Management Unit with MU variables using HDP, IOserv can crash with error message in dump involving MU variables management.
Having Reporter extracting data in the same time of a big HDP launch to a lot of MU with variables have been proven to catalyse this situation.
This (rare) behaviour has only been reproduced on Microsoft Windows (2003, 2008), however, it's not impossible that other OS could be impacted.
Environment:
OS: Windows
OS Version: All
Cause:
Cause type:
Defect
Root Cause: The way memory was managed when loading Management Unit variables values seems to have a defect which appears only under certain heavy load circumstances in Dollar Universe up to version 6.0.14.
Resolution:
This is fixed in Dollar Universe 6.0.15 and above.

Fix Status: Released

Fix Version(s):
Component: Application.Server
Version: Dollar.Universe 6.0.0
