[Tsung] tsung exits unexpectedly with load progression.

I have a problem with tsung exiting although it's work is not done.

 

I have defined a load progression like:

 

    <!-- warmup phase - 300 users in 30s  -40s -->

    <arrivalphase phase="1" duration="3" unit="minute">

      <users maxnumber="600" interarrival="0.1" unit="second"></users>

    </arrivalphase>

    <arrivalphase phase="2" duration="1" unit="minute">

      <users maxnumber="10" interarrival="10" unit="second"></users>

    </arrivalphase>

 

    <!-- 20 users/sec  - 600 users in 30s -80s -->

    <arrivalphase phase="3" duration="3" unit="minute">

      <users maxnumber="600" interarrival="0.05" unit="second"></users>

    </arrivalphase>

    <arrivalphase phase="4" duration="1" unit="minute">

      <users maxnumber="1" interarrival="10" unit="second"></users>

    </arrivalphase>

 

    <!-- 30 users/sec  - 600 users in 30s -120s -->

    <arrivalphase phase="5" duration="3" unit="minute">

      <users maxnumber="600" interarrival="0.033" unit="second"></users>

    </arrivalphase>

    <arrivalphase phase="6" duration="1" unit="minute">

      <users maxnumber="1" interarrival="10" unit="second"></users>

    </arrivalphase>

 

(there is actually one more with 40 users/sec, but we never get to
that.)

 

What happens is that tsung finishes at 210s.

 

I have attached my tsung.xml file (edited sessions) and the controller
log. 

 

When I define a load phase that will create 600 users with 10 users/s
for, say 1h - what does Tsung do? I would expect it to generate users
(10 per sec) and when 600 are reached reuse users so that we always have
600 users. It would be great if that was described in more detail in the
manual. 

 

 

Many thanks!
