[Steven Hawkins (Jira)]

    [ https://issues.jboss.org/browse/TEIID-5525?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13679538#comment-13679538 ] 

Steven Hawkins commented on TEIID-5525:
---------------------------------------

Followed up with TEIID-5584 to default enforceSingleMaxBufferSizeEstimate to false upstream as well.  Starting with 12.x we'll initially rely on intelligent session killing - but the user can enable this or the session maximum if they want more proactive enforcement.

> Several customers are seeing errors[1] after https://issues.jboss.org/browse/TEIID-4557 was implemented and generally have to drop the max-active-plans to 1 for their queries to succeed.  Can a flag be added to revert to the behavior prior to TEIID-4557?
