The Pi1 had problems with kernel panic in combination with high network load. Adding this parameter fixed it. I've noticed that the parameter isn't set in the current Pi2 images.

So perhaps give it a try:
Add in "/etc/sysctl.conf" the parameter "vm.min_free_kbytes = 16384" or a higher value "vm.min_free_kbytes = 32768".
Reboot.


You could also try the newest Pi2 standard firmware:

Terminal

sync
sync
sudo wget -O /boot/fixup.dat https://github.com/Hexxeh/rpi-firmware/blob/master/fixup_x.dat?raw=true --no-check-certificate
sync
sudo wget -O /boot/start.elf https://github.com/Hexxeh/rpi-firmware/blob/master/start_x.elf?raw=true --no-check-certificate
sync
sync

Reboot.

Thanks for your input
But this is the 1st time i have this problem and since i was using the rPis for viewing an average bit rate of 15Mbit/s x.264 files without any issue prior to the latest Kernel update it might not be the situation you describe.

Anyway i'm trying curly's idea and if it does not resolve the situation i'm going to try yours.

I hope avoiding my (multi) daily kernel panic freeze...

Please give us some feedback when you can.
thks.
