Hey Alex,

i think i also noticed something like this some time ago in our accounting, we 
use syslog output. I supposed that it had something to do with 
retransmissions, and that perhaps a really rare race condition exists 
somewhere in the accounting module. We take care of this in our cdr engine, so 
i did not debugged it further that time, as i don't had access to a sip trace 
showing the SIP message flow for the record(s) in question.

But if you say it has nothing to do with retransmissions, then its even more 
strange. How often do you observe this problem?

Regards,

Henning
