Hello, I confirm the issue is due to a memory leak but not in Heap zone but in Non Heap zone. I reproduced the issue. See :
- https://issues.apache.org/bugzilla/show_bug.cgi?id=52305 Issue is due to either a leak in rhino or in our JMeter usage of rhino. Workaround is to use expression in your IfController ${__jexl(${JMeterThread.last_sample_ok} == true)} Regards Philippe On Thu, Dec 8, 2011 at 9:58 PM, Stanton W Derry <de...@cpt.com> wrote: > ** > Hi Phillippe, > > Memory isn't an issue as there are no heap dumps for any of my runs.
