Auto configuration of buffermanager values can be incorrect
-----------------------------------------------------------
Key: TEIID-3635
URL:
https://issues.jboss.org/browse/TEIID-3635
Project: Teiid
Issue Type: Bug
Components: Query Engine
Affects Versions: 8.0
Reporter: Steven Hawkins
Assignee: Steven Hawkins
Priority: Critical
Fix For: 8.12, 8.11.3, 8.7.5
If the heap size is significantly larger than 2 gb, such that the auto computed value for
the max reserve is larger than 2 gb and the memory buffer size is also auto calculated,
then the computed values for max reserve and max memory buffer can be significantly
different than expected. At worst this results in the max memory buffer size of 0, which
just default the buffer to being accessible by a single thread.
