initconf never closes the ircd.conf file descriptor
by Juan Baez 26 Jun '09

I've been using my own modification of bahamut (solid-ircd) for a while now, and a user pointed out an issue to us, that applies to bahamut as well (1.8.6) included. The issue is that initconf never closes the ircd.conf file descriptor, so its essentially a memory leak as well. I checked out the latest bahamut via git-clone to test it out, and make the patch that's attached on this email. IRCd started under PID 31402 linux-cx9m:/home/jason # lsof -p 31402 | grep "ircd.conf" No file descriptors are open. So I sent out a SIGHUP. linux-cx9m:/home/jason # kill -HUP 31402 linux-cx9m:/home/jason # lsof -p 31402 | grep "ircd.conf" ircd 31402 jason 7r REG 8,3 4636 66269 /home/jason/ircd/ircd.conf Let's send out 11 mores just for kicks. linux-cx9m:/home/jason # lsof -p 31402 | grep "ircd.conf" ircd 31402 jason 7r REG 8,3 4636 66269 /home/jason/ircd/ircd.conf ircd 31402 jason 8r REG 8,3 4636 66269 /home/jason/ircd/ircd.conf ircd 31402 jason 9r REG 8,3 4636 66269 /home/jason/ircd/ircd.conf ircd 31402 jason 10r REG 8,3 4636 66269 /home/jason/ircd/ircd.conf ircd 31402 jason 11r REG 8,3 4636 66269 /home/jason/ircd/ircd.conf ircd 31402 jason 12r REG 8,3 4636 66269 /home/jason/ircd/ircd.conf ircd 31402 jason 13r REG 8,3 4636 66269 /home/jason/ircd/ircd.conf ircd 31402 jason 14r REG 8,3 4636 66269 /home/jason/ircd/ircd.conf ircd 31402 jason 15r REG 8,3 4636 66269 /home/jason/ircd/ircd.conf ircd 31402 jason 16r REG 8,3 4636 66269 /home/jason/ircd/ircd.conf ircd 31402 jason 17r REG 8,3 4636 66269 /home/jason/ircd/ircd.conf ircd 31402 jason 18r REG 8,3 4636 66269 /home/jason/ircd/ircd.conf linux-cx9m:/home/jason # ls -l /proc/31402/fd | grep "ircd.conf" | wc -l 12 This is a pretty easy fix, attach is a patch that fixes this. With the patch applied: linux-cx9m:/home/jason # kill -HUP 31761 linux-cx9m:/home/jason # kill -HUP 31761 linux-cx9m:/home/jason # kill -HUP 31761 linux-cx9m:/home/jason # lsof -p 31761 | grep "ircd.conf" No file descriptors are open. I don't see this being a "big issue," since flock is never called and the file is only open for reading. We've done quite a few rehashes ourselves and never really noticed this issue until it was pointed out. [root@vortex ~]# ls -l /proc/5047/fd | grep "ircd.conf" | wc -l 21 - Server Up 632 days, 2:30:22 End of /STATS report. - I seriously doubt that anyone will keep rehashing the ircd until the maximum number of file descriptors is reached. Can anyone else confirm this issue on their server(s)? Juan Baez

Problem with IRCServices and bahamut ("Services is currently down..." reply missing)
by Charalampos Pournaris 14 Jun '09

Hello, I am experiencing a problem with the lastest version of bahamut - 1.8(06) (also tried the git version with ssl support) - and IRCServices 5.1.17. When services are connected to the network, everything works as expected and I get a response for commands like "NS HELP" but If for some reason services quits the network (SQUIT, Crash) and I send a command to the services, I get no response, instead of the "Services is currently down. Please wait a few moments, and then try again." message which is expected. If I restart the IRC server with no services on network, the "services are missing" message shows up normally. It's not that the services crashes too often, but it is a good indication for users to know that services are down instead of no response. Thanks and regards, Charalampos Pournaris

There are many other softwares that support SSL. /Andreas
