Max Kuchin commented on GROOVY-7498:
------------------------------------
We also measuring GC time, it also increasing rapidly with groovy 2.3.11.
Please find a GC time chart here: http://i.imgur.com/vR12ibq.png?1
This web app was running with groovy 2.3.7 from Saturday till Tuesday, and with
groovy 2.3.11 from Wednesday till Friday.
Java heap usage is almost flat and doesn't depend on groovy version -

> Key: GROOVY-7498
> URL: https://issues.apache.org/jira/browse/GROOVY-7498
> Project: Groovy
> Issue Type: Bug
> Affects Versions: 2.3.11
> Environment: Ubuntu 14.04 , grails 2.4.5 java 1.7.0_80, tomcat 7.0.56
> Reporter: Max Kuchin
>
> We are experiencing JVM native memory leak after upgrading our web
> application from grails 2.4.4 (groovy 2.3.7) to grails 2.4.5 (groovy 2.3.11).
> It disappears if we replace groovy-all-2.3.11.jar in web application with
> groovy-all-2.3.7.jar.
> As a result of the leak JVM native memory usage can grow to 4G in two weeks
> after start of web application.
> We'd enabled native memory tracking (-XX:NativeMemoryTracking=detail) to
> gather some details. Here are results of native memory summary snapshot made
> with command jcmd pid VM.native_memory summary
> Native memory summary after start of application:
