             Bug #: 52064
           Summary: OutOfMemory Risk in CacheManager
           Product: JMeter
           Version: Nightly (Please specify date)
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: major
          Priority: P2
         Component: HTTP
        AssignedTo: [email protected]
        ReportedBy: [email protected]
    Classification: Unclassified


Hello,
I am doing some tests on an application that uses GET requests with a parameter
nocache generated for each request.
This application generates this request every second.

So I simulated this and ran an endurance test.

I noticed JMeter memory increased during the test.
I made a Heap Dump and saw that CacheManager was overwhelmed by this request.

There is of course an issue with WebServer config that should add Expires
Header but I think we should protect JMeter from this by limiting size on
Cachemanager HashMap,
as it is the case for a real browser that has a limited memory size for cache.
