Posted: Thu Feb 28, 2008 3:12 pm Post subject: segfault

Hello,

I am using icecast 2.3.1 in conjunction with ices 0.4.
the system is "Red Hat Linux release 7.2 (Enigma)"

Every few hours (it depends) the program segfault.

What can I do to fix it ?
If you need some more info, just ask Smile

Thanks in advance.

here is the debug I have with GDB:

Code:

Program received signal SIGSEGV, Segmentation fault.

Can you try the trunk code, just to make sure the problem is not occurring there. karl.

I've just compiled today's trunk and it doesn't start :

Code:

Starting program: /usr/src/icecast-trunk/./src/icecast -c /root/ice/icecast.xml
[New Thread 1024 (LWP 8898)]
Server startup failed. Exiting

Is there something I can do to have more info about the failure ?

the error log is one place, but if that is empty then send the xml to me (you can blank out passwords) and I'll check what can be done. karl.
