Hi! When doing a copy with many jobs that give access error i get a
really strange fault :
Thread 141 "python3" received signal SIG32, Real-time event 32.

This is git master @ c9622fd53 (Fix OSX build)
a dump log can be found here:
https://cernbox.cern.ch/index.php/s/JNaLKsaC5pyrhMP
which curiously did not segfault anymore
Any idea what could possibly be wrong?
What can i do to investigate this in more detail?
Thank you!!
Adrian
