Since this is an OpenBSD mailing list I recommend you build an OpenBSD system and run intree relayd, otherwise see below.
Does FreeBSD have a ports mailing list? If so I would recommend you posting your issue there. You could also try to contact the FreeBSD relayd ports maintainer. On Thu, 21 Nov 2013, ILIAS BERTSIMAS wrote:
Hello, We recently upgraded to the latest port version of relayd for FreeBSD 9.1 RELEASE-p7 and it started crashing unexpectedly. We had no issues with the older version and it was running stable for more than a year. The only thing in the logs is that: Nov 21 09:19:09 lb1 kernel: pid 20098 (relayd), uid 913: exited on signal 10 Nov 21 09:19:15 lb1 kernel: Limiting open port RST response from 201 to 200 packets/sec Nov 21 09:37:26 lb1 kernel: pid 20792 (relayd), uid 913: exited on signal 11 Nov 21 10:26:18 lb1 kernel: pid 23162 (relayd), uid 913: exited on signal 10 We upgraded for the new load balancing algorithms which we did not even start using yet.
