Trouble with streaming videowall


I have a problem with an 2x1 videowall horizontally with 2 HD222 that are playing a streaming video multicast UDP.
In the test environment it has worked for 12 hours without any problems.
In the installation it has been when they have begun incidents, totally random in time. The first few times, the right player, or slave, delayed the video a few seconds, when you restart your streaming, was returning to work all fine until after a few hours again was returning to fail, and the last, is that right monitor, image was to black, as if there were no streaming, restart the streaming, it works, but soon was returning to fail.

Thanks!

P.D.

On the player on the right screen, in the log, is repeated several times this:

[20408.165] FireEvent 26 (line 517)

    I don't know if you forwarded this issue to our support email as well. The masters and slaves communicate with each other using broadcast and if the switch/router is delaying or blocking traffic between the units, you can get poor performance. If the switch has igmp snooping enabled, please disable it.
