asterisk users - Dec 2005 - asterisk 1.2 mysql cdr garbage

hi,

Just wanted to know if anyone else is experiencing 'garbage' mysql call 
detail records on asterisk v1.2?

So, where the ? is, tehre should be a number..

Example:
1. 2005-12-16 10:07:08   Local/210@...   ?  	"400Tech:" <?> 
210  	ANSWERED  	00:00
2.  2005-12-16 10:02:43  SIP/206-69... 	? 	"400Tech:" <?> 	210 
ANSWERED 	04:25

If I restart asterisk, this is solved for a few hours..

Cheers,
Kristof.
