So it crashed.. and you have a core file? (without it, we are pretty helpless :P). Assuming so, do this: - gdb src/ircd name.of.core.file bt - |

i just uploaded the output of bt in gdb, with the 2 ip addresses replaced of course :) had to gzip it because it was over 20000 lines long (basically just the same thing repeated many times) |

Ok, that helped. It looks like the junk snomask (snomask +j) itself is the problem (that's where the SSL error message is sent to). An error is encountered when sending a message (connecting msg in this case, but irrelevant) to 'amber', which causes an error message to be sent to... amber, which causes a message to be sent to... well, you get the idea ;). This should be an easy fix, I'll get back to you soon. |

This simple patch should fix it: http://www.vulnscan.org/tmp/sslcrashwithjunksnomask.patch To apply the patch: 1. Go to your Unreal3.2 directory 2. Type: cat /path/to/sslcrashwithjunksnomask.patch|patch -p0 3. The above should not give any error 4. Recompile Unreal: make && make install Looking at the code, I'm pretty sure this fixes it, but please let me know as soon as possible in case you crash with this fix too (just drop a quick email to [email protected]). I'll put this fix in 3.2.4 (and/or next rc) also. |
