[OpenSIPS-Users] High load average due to mi_datagram's sockets

I noticed a strange load average on my system. When the system was idle, I
had a load of 4.00. It turns out that it's directly related to mi_datagram:s
children_count. I had 5, and the load was 4. Lowering to 2 I got load 1.00,
lowering to 1 I get 0.00, increasing to 20 I get 19.

This is on an idle system (no calls), with nothing but a "regular" setup of
Opensips + Mediaproxy (w/ radius and cdrtool).

What could possible cause this?

modparam("mi_datagram", "unix_socket_mode", 0666) # same without this row
modparam("mi_datagram", "socket_timeout", 2000) # same without this row
