| Summary | 0004366: listener gone, logging stopped | ||||
| Description | Hm not sure. Strange random issue... may need some attention. Port was suddenly closed (like the listener stopped working). Similarly: *** Notice -- WARNING: Unable to write to '/home/irc/unrealircd/logs/ircd.log': Broken pipe. This warning will not re-appear for at least 5 minutes. Rather unusual error, "Broken pipe", for a log file. I'm just reporting it here, in case others see it, amd/or so I can try to reproduce later. | ||||

I think I just had it again. Nothing was logged but I was able to start a 2nd ircd instance that bound to 2 out of the 5 listeners that should have been taken by the 1st (an ircd launched yesterday). So apparently 2 out of 5 were closed by the old ircd. Better add some debugging code for this... or something... it's bad. |
|
|
marking as confirmed, even though it's only me & random. |
|
|
Ah, I did have one port that didn't bind on boot (that was correct, it is in use by something else). Maybe that will confuse things further up? It's closing the wrong fd somewhere I think, anyway. Seeing how it affected both logging and TCP/IP sockets. |
|
|
Hmmm.. haven't nailed this one yet. Played a bit with an unbound port, rehashing and stuff, but no problem. I did find a close() for non-existant FD caused by nenolod's code, but I actually don't think that was the cause. |

[21:35:31] -maintest.test.net- *** Notice -- No response from services.test.net[127.0.0.1], closing link [21:35:31] -maintest.test.net- *** Notice -- WARNING: Unable to write to '/home/syzop/unrealircd/logs/ircd.log': Broken pipe. This warning will not re-appear for at least 5 minutes. lsof shows the log file is no longer open. I did have a gdb session attached at that time, though... maybe related. ^^ yeah broken pipe log file error may be unrelated. I can cause that with gdb easily. |

Had it again. no valgrind, no gdb... booted ircd, tried to link in another ircd (this link was incoming), auth failed, fixed the link block on the other side, then had 'connection refused' -- huh? yeah... the listener was gone again. nothing in logs. Bad. NOTE: This is with all the abort() code in fd_.... enabled. |
|
|
Just had no logging.. was caused by the mass close fd code. I've removed it now. it was doing a close(3), so fd 3 was later suddenly a socket (possibly from c-ares.. not important), and then it was write()'ing logs to that fd which triggered the 'broken pipe'. Makes more sense for a socket, that error :D |
|
|
I *hope* this is fixed now. |
