Hi Daniel
Yes, a "fake" signalling channel is a work aound. The patch below is also a
work around..

+++ cluster.c 2007-03-23 09:51:25.000000000 +0100

- if (this_host->has_signalling_receivers)
- if (setup_receiver_socket())
- goto fail;
+ if (setup_receiver_socket())
+ goto fail;
connect_receivers();
receivepipe[0] = receivepipe[1] = -1;
receivebuf = lffifo_alloc(200000);
Best regards
