RANADEEP SHARMA created CXF-6938:
------------------------------------
Summary: Unwanted bunch of Bus Provider objects in HashMap
occupying large volumes of heap memory
Key: CXF-6938
URL: https://issues.apache.org/jira/browse/CXF-6938
Project: CXF
Issue Type: Task
Components: Bus, JAX-RS
Affects Versions: 3.1.6, 3.1.0
Environment: Redhat Enterprise Linux (Santiago), OpenJDK 7, Tomcat 7
Reporter: RANADEEP SHARMA
We have an application with REST client components for making calls to Backend
web services. During our routine performance test, JProfiler tool shows lots of
Bus property entries (with keys named "bus.providers.set.<hashCode>") populated
while creating instances of ClientProviderFactory.
These Bus property entries seem to stay in heap for the whole duration of the 6
hour run. In fact, around 100,000 entries occupying 13 MB of heap.
In short, GC doesn't seem to happening frequently enough to keep the heap usage
within limits.
Is this some sort of a bug or, lack of necessary configuration in CXF?
Either ways, we need your guidance for trouble-shooting this issue.
