Re: HTTP Interface gives segmentation fault

Hi,

first of all, if you have segfault please file a bug report for it...

You can try to set: ulimit -c  in your start script and enable debug level (0) 
for bearerbox. Last ~100 lines of debug log would get possible place that 
cause segfault. 
For the 'ulimit -c', you can add to your start script lines like this:
	cd /my_place_for_coredump
	ulimit -c 10000
	bearerbox ...

Please note that you should compile your bearerbox as well smsbox with '-g' 
gcc option, like this: CFLAGS="-g" ./configure ...

Good luck!
