Tvheadend

Hi all,

I am very new here and had some great help with setting up tvheadend from a friend.
However I updated to the version 3.9.2514~g50016a1 for the new transcoding options and now I find that my server becomes very slow, unworkable even.

In the log I see a lot of "....udp:....-- deleting" :

Mar 14 21:47:47 server tvheadend¹³⁰²³: mpegts: udp://224.0.251.43(null) in IPTV network (0x2818b00) - deleting

When I stop TVHeadend the server functions normally again, there are no hanging processes on the server

My setup:
Unbuntu 12.04 Server
8 gb memory
2 networkcards

I know it is very little info thusfar, but maybe it is just a setting somewhere.
Attached is the LOG. If I need to add more info, please tell

Thank you in advance
