Hemanth Yamijala created ATLAS-471:
--------------------------------------
Summary: Atlas Server could run out of memory due to Scala memory
leak
Key: ATLAS-471
URL: https://issues.apache.org/jira/browse/ATLAS-471
Project: Atlas
Issue Type: Bug
Reporter: Hemanth Yamijala
Priority: Critical
We noticed our servers running OutOfMemory occasionally, particularly under
heavy query loads. Profiling the app with YourKit, I found a lot of instances
of {{scala.util.parsing.combinator.Parsers}},
{{java.lang.ThreadLocal$ThreadLocalMap}} and
{{org.apache.atlas.query.QueryLexer}} objects. These object counts increase
steadily over time as seen after taking multiple snapshots.
