Hi Tim, Thanks again for your answer. I already thought so, however, in my case the stack level increases over time It starts with zero I see it decrease some times, but after 1000 log lines it already is at 262
So I guess this smells like a nesting problem? I have to find out where and why Or could there be another reason?
