OMEdit (1.9.0 beta4+dev 15786-1) frozen with 100% CPU load

I just want to mention my latest experience.

The problem seems related to Debian Wheezy and KDE. If I use another Desktop Environment
( I tried icewm) the problem vanished current/smile and OMEdit works like a charme.

Starting a fresh KDE Desktop environment for an new created user will not solve
the problem.

Also the experiment to copy the OMEdit executable together
with all shared libraries from a Ubuntu 12.04 system to my Debian box, didn't
help.

I wonder if OMEdit is working on a Kubuntu system. Maybe somebody else can try ..

For now I have found a workaround and I can concentrate my work
on developping Modelica Simulation models.  current/smile

OMEdit (1.9.0 beta4+dev 15786-1) frozen with 100% CPU load

Thanks a lot. I  installed all packages from the new repository and
everything is up to date

apt-cache show omc | grep ^Filename:

    Filename: pool/contrib-wheezy/omedit_15947-1_i386.deb

Unfortunately the problem still remains. I tried again:

Mechanics.Rotational.Examples.First:

  After the simulation run I have to wait approx 5 minutes. Then CPU load went down and
  I could use the plotting view. After switching to modeling view and  back to plotting 
OMEdit was frozen agein.

  similar (but not exactly reproducable) results happen with other examples (Blocks.Examples.PID_Controler)

Next I would like to test OMEdit on a fresh installed Ubuntu distribution.

Do you have suggestions how to  track down the problem?

Meanwhile I terminate OMEdit after the simulation run, read the mat file
with octave and do plotting from there.

Thank you for your help

OMEdit (1.9.0 beta4+dev 15786-1) frozen with 100% CPU load

thank you for the hint. Hmm I believe it worked 2 week ago .. .
Anyway I changed it  to

deb   http://build.openmodelica.org/apt squeeze nightly

and got an update to Version: 15923-1.

unfortunately the problem remains the same. Do you think
I should compile everything from source?


$ apt-cache show omc                                                                                                                   

Package: omc

OMEdit (1.9.0 beta4+dev 15786-1) frozen with 100% CPU load

After running example models (Mechanics.Rotational.Examples.First and others)
the statistic message window pops up, the view changes for  plotting but
OMEdit is frozen with a CPU load of 100%.

I already checked:

   omc processes are running

   /usr/bin/omc +c=OMEdit109ba09837000136729992600000060720044073207235 +d=interactiveCorba +locale=de_DE
   ...

   the last entry in omeditcommands.log: readSimulationResultVars(...) Elapsed Time :: 0.044 secs

   strace -p <pid of OMEdit> shows that the process is writing all the time
   write(7, "\1\0\0\0\0\0\0\0", 8) = 8

   system has enought memory, it is not swapping


I installed OpenModelica (nightly build) on a i386 Debian/Wheezy from

      deb http://build.openmodelica.org/apt nightly contrib

OMShell OMNotebook are running nice.


Any suggestions?

Wolfgang
