----------------------------------------------

Hello,

Do you use unistim channel and what is your unistim.conf configuration? In case you do not use it, probably you have a lot of unexpected UDP traffic received by chan_unistim. You need to check incoming traffic, disable chan_unistim or configure firewall.
