The symptoms are: sporadically, some jobs abort with a job log that says "Cannot load environment".
On the Univiewer Console, the action button "Could not Submit" appears on those executions.
A simple relaunch of this job allows the job to Complete successfully.

In the job log of the Aborted Jobs, the following kind of messages appear:
Cannot load environment
The syntax of the command is incorrect.
The issue was due to a Windows bug that affected the creation of a process sporadically.
We have had the feedback from several customers that updating the Windows 2012 servers with the last KBs from Windows Update has allowed to completely erradicate the issue.
We still don't know exactly what is the KB containing the fix, but should be one of these two: KB3192884 (MS16-120) or KB3175024.
Please ask your Windows System Administrators to apply those KB on the impacted systems.
