> Ambari Server REST API Memory Leak
> ----------------------------------
>
> Key: AMBARI-7221
> URL: https://issues.apache.org/jira/browse/AMBARI-7221
> Project: Ambari
> Issue Type: Bug
> Components: ambari-server
> Affects Versions: 1.6.0
> Environment: Oracle JDK 1.7.0_45 on CentOS 6.5 64-bit
> SLES 11 SP1 64-bit with Oracle JDK 1.7
> Reporter: Jonathan Hurley
> Assignee: Jonathan Hurley
> Priority: Critical
> Fix For: 1.7.0
>
>
> PROBLEM: When running many 1000's of REST API calls, the heap memory usage of
> the Ambari server slowly goes up. Forcing a garbage collection will reclaim
> some of the heap but it never goes back down to its starting level.
> Eventually the JVM is forced to do a full GC which hangs the Ambari server
> for several minutes and, again, doesn't free all of the heap used by the API
> calls.
> The Ambari server stopped working with out of heap space messages.
> STEPS TO REPRODUCE: I was able to reproduce the issue using this simple
> script run on the Ambari server machine:
> {{while [ 1 ]; do curl -u admin:admin http://localhost:8080/api/v1/clusters;
> done}}
> ACTUAL BEHAVIOR: Ambari server heap memory usage increases over time when the
> REST API is used repeatedly. GC does not free it.
> EXPECTED BEHAVIOR: Memory used by REST API connections should be released
> after a GC.
