| Summary | 0006435: io.BUG_FD_SETSELECT_OUT_OF_RANGE | ||||
| Description | I was running unreal on a RHEL7 machine, and recently created a series of Docker containers to run everything instead. I was running a fairly recent version until then (6.1.4) and had never seen this error. But in the last couple days randomly it pops up now (using 6.1.7rc1, I haven't rebuilt the image since the official release): ``` 12:28:55 [srhuston.net] !irc.srhuston.net blacklist.BLACKLIST_HIT [info] [Blacklist] IP 162.142.125.209 matches blacklist dronebl (dnsbl.dronebl.org/reply=6) 12:28:55 [srhuston.net] !irc.srhuston.net tkl.TKL_ADD [info] G-Line added: '*@162.142.125.209' [reason: Proxy/Drone detected. Check https://dronebl.org/lookup?ip=162.142.125.209 for details.] [by: irc.srhuston.net] [duration: 1d] 12:28:56 [srhuston.net] !irc.srhuston.net io.BUG_FD_SETSELECT_OUT_OF_RANGE [error] [BUG] trying to modify fd -2 in fd table, but MAXCONNECTIONS is 16384 ``` It's not just related to blacklist or gline operations though: ``` 09:46:49 [srhuston.net] !irc.srhuston.net blacklist.BLACKLIST_HIT [info] [Blacklist] IP 167.94.145.101 matches blacklist dronebl (dnsbl.dronebl.org/reply=6) 09:46:49 [srhuston.net] !irc.srhuston.net tkl.TKL_ADD [info] G-Line added: '*@167.94.145.101' [reason: Proxy/Drone detected.

Could you share the output of /VERSION as an IRCOp with me? (This would share library versions and such) Thanks! |

Thanks for the info. If you want to help me more then could you either upgrade to 'git' (and restart the ircd) Or.. if you don't want to upgrade to git, then do the following: cd unrealircd-6.1.7-rc1 wget https://github.com/unrealircd/unrealircd/commit/b39b953b8ec6aad293d94348d115442868648c46.patch patch -p1 <b39b953b8ec6aad293d94348d115442868648c46.patch make clean; make install And yeah, it does require an IRC server restart unfortunately. It will, however, if this issue happens again, print out exactly which file:line is triggering this bug, narrowing it down from 50 locations to 1 location. So that would help me a lot. |

Ah, fixed the bug in git just now. Will probably release 6.1.7.1 later. And yeah, the warning was harmless. |
|
|
Ah, great! Upgrading to git wouldn't have been a problem, that's actually what the container build process does (a clone --depth 1). But now I'll wait until the release notice instead. Thanks! |

Fixed in UnrealIRCd 6.1.7.1, released just now. Thanks for the report and your help :). https://github.com/unrealircd/unrealircd/commit/0496c35fc6bac015247738c95e05fa503f63697d is the actual fix commit |
