Another 11.3.x surprise we found was related to the Workload Management feature, or WLM. Others may have run across in 9.1.x, which we skipped...
In our first pass at setting up an 11.3 server, we had a minimal amount of physical memory, although it may have been more than the minimum recommended.
The WLM feature was activated by default, and with a default threshold of requiring 80% free memory before running any jobs. So, the very first handful of test jobs we tried to run just sat there with a Queued status until we figured out why and updated the setting. Later, we added more memory.
