do you get same situation with syslog acc? As I understood Alex got it 
with db accounting.

What is very strange in Alex's case is he gets it with db and not with 
syslog, for same event. The module calls step by step syslog and then db 
recording. So if there would be 2 db records, should be 2 syslog records.
