Large File Support

I've been testing lately with a smpp simulator, and getting 2GB kannel log files can typically happen, 
and then kannel seems to just stop..........
after a bit of reading it appears as if you need to do some things
http://www.suse.de/~aj/linux_lfs.html

just wondering if anyone did such with kannel, and what the results are?

though I will probably just truncate my logs more often!!
