Thanks for the report. Could you send over the following files to [email protected] or upload them somewhere and post a link? 1) The file named 'core' 2) The ircd binary, usually 'src/ircd' 3) commands.so, usually 'src/modules/commands.so' This would enable me to look into this crash in more detail. Thanks! |

Email sent—thanks for looking into this! |

Thanks a lot. There seems to be a problem in 3.2.10's I/O engine. I'll verify my theory & find a proper solution and (stress) test it... this may take a few days as I have to work extra at my other (paid) job. The final solution is probably only to change a few lines, but of course this needs to be done with great care.. don't want to create a new issue when resolving the first one :) Thanks again for the core dump and other files, this helped a lot. |

|
Just an update: it crashed twice today again. If you'd like more core dumps, I can provide them. |

If you can, try this patch: http://www.vulnscan.org/tmp/3.2.10.1-f1.patch On the shell you type, in your Unreal3.2.10.1 directory: patch --dry-run -p1 </the/location/to/3.2.10.1-f1.patch If this does not raise any alarm bells (should be just 'Patching ...' with some possible 'FUZZ', nothing else), then run the command for real: patch -p1 </the/location/to/3.2.10.1-f1.patch Once the patch is applied, re-run 'make', and 'make install' The IRCd then needs to be restarted, unfortunately a /REHASH or reload is insufficient. This patch actually addresses a number of issues. Let me know your results, especially if they are negative ;) |

Just applied the patch and restarted the server: so far so good. Sometimes it would take a number of days for the bug to manifest, so I'll keep monitoring it. |
|
|
Ok, thanks :) |
|
|
After a week, the IRCd is still stable. Thanks for taking care of this issue so quickly! |
|
|
Great. Thanks for letting me know. |

Thanks for your help in this, really appreciated. This issue has been resolved in 3.2.10.2 (using the same patch as linked earlier) |
