I got this error message in /var/log/messages when trying to start iotop:

Apr 13 08:49:37 hostname kernel: grsec: From denied RWX mprotect of /lib64/ by /usr/bin/iotop[iotop:9836] uid/euid:0/0 gid/egid:0/0, parent /bin/bash[bash:9351] uid/euid:0/0 gid/egid:0/0

/usr/bin/iotop is a Python script and according to that log message grsecurity detected a call to mprotect().
