Hello,
Since i installed rtpengine, I have many messages like "UDP: bad checksum".
[383818.303391] UDP: bad checksum. From x.x.x.x:7272 to x.x.x.x:45898 ulen 58 [383819.671083] UDP: bad checksum. From x.x.x.x:7272 to x.x.x.x:45898 ulen 58 [383819.943360] UDP: bad checksum.

Do you have any idea where to start investigating?
Env:

This is not a problem of rtpengine, either the checksums of the incoming packets are corrupt or the checksumming in the kernel is getting corrupted (could be a kernel bug or an ethernet card/driver problem in the case of offloading (see ethtool options to disable if possible)).
