Hi,

I'm having a problem with one of my test plan.
The test plan contains two thread group:
-One simulating a "normal" usage of the server (1000 threads in 2000 s.)
-The other one simulating a "peak" during a short periode (500 threads in 100s)
-A "constant timer" has been added between the two threads.
-Both threads are a "Aggregate Report" with the same data file (aggregate_report.jtl)

Is that the cause of the problem ?
