Hi,
my KXstudio 12.4 version has a big problem with Loomer and pianoteq plugins.

In former times everything went.

Yes, realtime kernel is running.
..@gemini:~$ uname -a
Linux gemini 3.10.10-rt7 #1 SMP Wed Oct 2 20:04:44 CEST 2013 x86_64 x86_64 x86_64 GNU/Linux

When using pianoteq as standalone program, it works two minutes and then the computer freezes.
When using loomer apps as standalone program sometime the computer freezes immediately, sometimes it freezes when opening the menue in the app.

Yesterday I test last ardour version with the new overtonedsp linuxVSTplugins. Everything was working fine.
Today I load a song to ardour with String and Aspect as plugin, I have made last year. System freezes after maybe two minutes.

thank for help
Chris

Thanks,

I try 3.8.0-32-lowlatency kernel and it seems to work fine.
The realtime kernel have little bit better performers on my old computer but lowlatency work too.

thank you very much.
