Also gtm_slave fails to start. We are using nonstandard gtm/gtm_proxy ports, but it does not look like a problem..

if (my_threadinfo->current_number >= my_threadinfo->max_lock_number) { abort(); }

Both current_number and max_lock_number are 0.

gtm_proxy is no longer needed for tbase.

Thanks for confirmation, we disabled proxies. Do you plan to update pgxc_ctl/guc.c code to take it into account?
