Hi Tomasz, I don't think it's related to cpum changes (it's another executable).
How much users are you using per instance ? Are you saturating the TCP interface ? (even if it doesn't seems to be a high CPS)... Can you also check the cpu utilisation on the sipp/manager side? (ex: using top) The message means that we have prepared calls 2 seconds upfront (PrepOffset), and once it's supposed to be really executed; we don't have calls in the SYNC (=ready) state. One way to debug it is to start sipp instances manually (not in background), so you can check the screen and get more detailed information about the calls states.

As for now, I haven't made enough tests to make sure that it is related to this change. I'll switch back to old version. Do you know if such effect could result from these changes? I'm attaching logs. The "frozen" sipp stops updating its screen (even the Total-time counter doesn't go forward). It happens to all sipp instances (I have 4 of them). After the sipp "freezes", the manager only prints CPU stats, not call stats. Neither sipp nor manager responds to "q" key, but they both respond to Ctrl-C. However, stopping manager with Ctrl-C doesn't stop sipp as it normally does. Characteristic entry that repeats many times in sipp logs: !! ERROR !! There should have been calls in SYNC !!. Full logs are attached. I'll appreciate any help -- Tomasz Radziszewski Senior Software Engineer Ericpol Telecom sp. z o.o.
