[teiid-issues] [JBoss JIRA] (TEIID-3635) Auto configuration of buffermanager values can be incorrect

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, 8.7.8.6_2 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.
