 Ok, it seems, that here is a problem (CPU time :

PID USERNAME PRI NICE   SIZE    RES STATE    TIME   WCPU COMMAND
 12 root     -16    -     0K     8K sleep   18:35 30.18% ng_queue

 And after that 5 minutes without updates, than normal numbers. It
seems, that root of problem is:

 (a) netgraph in this version of kernel
   OR
 (b) new mpd 5.6 (previous version had 5.5).

P.S. Adding net@ and mav@ to CC, original posting with all data is in
current@
