Hi I am trying to run on openSUSE Leap 42.1 x64 from Python. When I try to create a SIP account lib.create_account(account_config) I get the error below Traceback (most recent call last): File "gevent/_semaphore.py", line 101, in gevent._semaphore.Semaphore._notify_links (gevent/gevent._semaphore.c:2030) link(self) # Must use Cython >= 0.23.4 on PyPy else this leaks memory error: cannot switch to a different thread (<built-in method switch of Greenlet object at 0x7f367d897f50> <gevent.thread.LockType object at 0x7f367cfc57c0>) failed with error Before calling the function above I have registered the current Python thread with lib.thread_register(name) I have used previously with success PJSUA Python module. Does anyone know how to solve this problem ? thanks Bogdan _______________________________________________ Visit our blog: http://blog.pjsip.org pjsip mailing list pjsip@xxxxxxxxxxxxxxx http://lists.pjsip.org/mailman/listinfo/pjsip_lists.pjsip.org
