sorry for delay, being offline for some time...

This is interesting as you say there is no traffic on server. Since is a 
testing system I guess we can play a bit with it. The error might be due 
to a bug in FIFO command parsing or a bug in printing the command to 
fifo file.

The best is to add a debug message that will print the entire fifo 
command received by kamailio. Should I do a patch for you?

More strange is with dialog value as there is no traffic, that value 
should not be affected at all and should be zero. If you do kamctl 
get_statistics all from command line, do you get same value?

Thanks,
Daniel
