RANADEEP SHARMA commented on CXF-6938:
--------------------------------------
Hi Sergei,
Could you please comment your experiences on performance analysis of the
module. I am sure other users must have reported similar issues.
I am just trying to get some directions on how to narrow down the scope for
trouble-shooting since you guys developed the library.
Regards,
Ranadeep.
> 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: 3.1.0, 3.1.6
> Environment: Redhat Enterprise Linux (Santiago), OpenJDK 7, Tomcat 7
> Reporter: RANADEEP SHARMA
> Assignee: Sergey Beryozkin
>
> 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.
