TOPIC: Trisul segmentation fault error

Re:Trisul segmentation fault error 12 years 1 month ago #671

Thanks Chris,

Lets nail this today :-)

I uploaded the latest 2.4 build along with a trisul executable with debug symbols.

1. Download the new trisul DEB (version 2.4.1067 ) from trisul.org/download/
2. Uninstall the old one (dpkg -r trisul)
3. Install the new DEB
4. Download the trisul.gz executable file containing the symbols
5. Gunzip the downloaded trisul.gz into /usr/local/bin (you should have a file called /usr/local/bin/trisul )

Now run the same way.

gdb /usr/local/bin/trisul
(gdb) r -nodemon <etc etc>


Now when the segfault happens you can type bt (Backtrace) or where

Also do you see anything funny in /usr/local/var/log/trisul ? Can you send me the latest log file by email to vivek at unleashnetworks dott com ?

Also feel free to contact me directly by mail. I really appreciate all your help with this.
