OK accorting to your expertise this could be somethning wrong in some of the DSOs ..

May I ask for a little help with pointing on possible module which i doing sometbing wrong?

Just looking on top of the call trace

I don't see any DSO module code on that call trace (?!?)
May I ask help with assesment which one module may be messing here?

Thank you for any help
