Device or resource busy

Hi all. I using gnokii 0.6.32 from git On ubuntu 12.4 i366. Phone: Nokia 
5130 XpressMusic and running smsd with mysql. When smsd is running, I 
can not use any command gnokii:

# gnokii --monitor delay
GNOKII Version 0.6.32git

Perhaps it has something to fix it? (Sending SMS messages and receiving 
is good running)
