             Summary: Buffer cleaner running too often in some cases
                 Key: TEIID-5422
                 URL: https://issues.jboss.org/browse/TEIID-5422
             Project: Teiid
          Issue Type: Bug
          Components: Query Engine
            Reporter: Steven Hawkins
            Assignee: Steven Hawkins
             Fix For: 11.1, 11.0.1, 10.3.3


As observed in TEIID-5418 when the buffer cleaner runs too often it causes thrashing by pushing out pages that get reused close to the cleaning interval of 100 milliseconds.

Increasing that interval to at least beyond the default time-slice will consume more heap - but the cleaner will still be engaged when a processing thread must clean beyond the max allowed.
