[grsec] Debug output?

[John Anderson]

We are still testing our installation of GRSEC on certain boxes, and 
after the upgrade to 2.1.3, we starting seeing some strange behavior.  
Whith grsec up and running, if a user access a program, like vim or ls 
or whatever, we get some debugging information (I think) printed to the 
console.  Vim still executes and runs properly however.  It looks like this:

Mar  7 15:35:32 bastion-dev kernel: grsec: From 10.20.27.18:

Is this normal, expected behavior, or is it debugging output?  If it's 
debugging output is there a flag that can be set to turn it off?

Thanks again,
