Both under OpenBSD 5.0 and OpenBSD foo 5.1 GENERIC.MP#188 i386
relayd dies under load. The setup is very simple: redirect http.quotes.netfonds.dk { listen on 192.168.0.10 port http interface em0 tag RELAYD forward to <webhosts> port 9204 check http "/foo" code 200 } relayd comes up as normal: host 80.91.234.141, check http code (37ms), state unknown -> up, availability 100.00% host 80.91.234.142, check http code (37ms), state unknown -> up, availability 100.00% and I can run apache-bench successfully: $ ab -n 1000 -c 20 http://192.168.0.10/foo But after doing this a few times, relayd invariably dies, first saying that the web servers are down: host 80.91.234.141, check http code (0ms), state up -> down, availability 83.33% host 80.91.234.142, check http code (0ms), state up -> down, availability 83.33% relayd in free(): error: bogus pointer (double free?) 0x7d716800 lost child: hce terminated; signal 6 pfe exiting, pid 9938 -- (domestic pets only, the antidote for overdose, milk.) bloggy blog http://lars.ingebrigtsen.no/
