| Summary | 0002675: unreal unexpectedly crashed | ||||
| Description | My ircd just died today. No source modifications, the only third party module used is cgi:irc but I'm using that since almost two years without problem. I recently recompiled the ircd due to the libcurl security issue (compiled with newest libcurl). Don't know if this has anything to do with the problem. The ircd.log doesn't say a word about unreal crashing. | ||||

Follow the instructions Syzop gave me in 0002515 to produce a better backtrace (the first 2 bugnotes). |

True, though.. I see where we are getting at already. Every time someone reported a crash that was in remove_client_from_list or some other client list related routine, the person was using this CGI:IRC module (or something based thereon). I therefore still expect it is related to the CGI:IRC Module and not Unreal. |

ok, i followed instructions Bugz suggested me: Core was generated by `/home/ircd/unreal-rock/src/ircd'. Program terminated with signal 11, Segmentation fault.

Mass cgi:irc bug close. These crashes are related to cgiirc, and thus "not our fault" ;). All servers with a crash in hash_find_server (bugreports: #2529, #2657, 0002675, and more) were using the cgiirc module. This can't be coincidence. |
