Error when quickly browse Recordings on frontend with a Intel Network Card

[ernst.reiter@…]

Hi,

I got a new main board on my Backend server with a Intel network card (igb.ko Kernel module). What happen if i now quickly browse the recordings from a remote Frontend the frontend displays a message with a big green tick: "myth context: backend is online". several times and the scrolling is stuck a couple of seconds.

Anything else on the Frontends are working correctly. I tried to switch to a different Network Card (Realtek Chipset) and everything is got working correctly. Switched to a different Intel Card (e1000e.ko) - got again the error.

So it has something to do with the intel cards/kernel modules in combination with mythbackend. Anything else is working fine on the Network Card - including Gigabit performance.

Following errors are appear on the Backend, when this error occurs: Jan 6 17:25:31 myserver mythbackend[7332]: E MythSocketThread?(43) mythsocket.cpp:790 (ReadStringListReal?)

Kernel is 3.11.6-4

BTW: It is the same issue as discussed here: ​http://www.gossamer-threads.com/lists/mythtv/users/559379?do=post_view_threaded#559379

The frontend is losing it's connection to the backend - Looks like a bad network card or driver.
