Hi Peter! I need help again debugging this issue. I used c++filt to beautify the trace. I also added the log lines before -> see attachment.
I do not understand how the stacktrace correlates with the exception error. I analyzed the stack trace and I do not see any access to a DNSName at the top of the stacktrace. May it be that the exception and stacktrace do not correlate, eg. the exception causes some exit code, the exit is caught by the signal handler, something goes wrong (signal 11=segfault), and then a stack trace is generated of some other thread which does not correlate with the origin exception? Thanks Klaus
