Stop running bad programs. :*
If the app is written using a tool like java/mono or something like
this, it may be required.
You have two choices you can either label it execmem_exec_t.
# semanage fcontext -a -t execmem_exec_t PATHTOMYPROGRAM
# restorecon PATHTOMYPROGRAM
Or you can turn the check off altogether by executing
# setsebool -P allow_execstack 1
Thanks, Daniel. Let me add some more information:
