VM will try to fix the stack guard now - 'execstack -c '
What does this mean and how can I resolve this? I'm using g2.2xlarge instance and running transcoder application
INFO server comment - TranscoderSessionNative.loadLibrary: Load transcoder list file: /usr/local/WowzaStreamingEngine/lib-native/linux64/transcoder.list
Java HotSpot(TM) 64-Bit Server VM warning: You have loaded library /usr/local/WowzaStreamingEngine-4.0.3/lib-native/linux64/libmc_bc_dec_avc.so which might have disabled stack guard. The VM will try to fix the stack guard now.
It's highly recommended that you fix the library with 'execstack -c <libfile>', or link it with '-z noexecstack'.

Please provide step by step instructions if possible.
Assuming you are going to use edge servers to re-stream from, be aware that using the Internal DNS to connect edges to the origin will provide greater network utilization of the origin's 10gbs nic. However there is a 5gbs Java limit. The only way to utilize more is to have two instances of Wowza and Java running on the server, but since you can only have one IP on that kind of EC2 instance (I am pretty sure) you would have to use alternate ports on the 2nd instance, so it is not very practical.
