I would bet on a massive threads creating/deleting testcase signalling tasks around, together with watchpoints. There are races in the linux-nat code and IIRC even gdbserver code. OTOH if one tries hard one can probably manage one day to fix all the corner cases in the ptrace based linux-nat and gdbserver. Regards, Jan
