[Freeswitch-users] Can't get debug to stop

Hi, I enabled debug and SIP trace via: export SOFIA_DEBUG=9 export NUA_DEBUG=9 export NTA_DEBUG=9 export TPORT_DEBUG=9 export TPORT_LOG=1 I then tried to unset the vars, and also export SOFIA_DEBUG=0 and so on. Still the SIP traces are on the screen. I exitied screen and tried again still no go. What am I doing wrong? Im running bash on FreeBSD. Any help would be great, id have to reboot this box just cause I cant figure this out! Thanks
