[SR-Users] [kamailio-users] kamailio on amazon

[samuel]

hi all,

Which is the kernel version of the amazon instance? There was some minnor
net issues with incorrect checksum that affected 2.6.18. You can disable the
checksum with ethtool

ethtool -K [intercace] tx off

Try above command and check whether the debug message disappear.
Hope it helps,
Samuel.
