As noted on the ports mailing list, after 6.0 upgrade/cvs source/build 
kernel/build world/pkg_add -u I am experiencing
wx violations on a single whole-disk label mounted as / wxallowed.

Solène Rapenne <sol...@perso.pw> posted:

On -current binaries now needs both wxallowed on their mountpoint AND have to 
be compiled with -wxneeded flag.

Maybe this has been backported to 6.0-stable ? I don't know where to look to check that. Maybe someone have a clue ?

Any tips?

Example errors from dmesg:

seamonkey(89184): mmap W^X violation
java(79321): mprotect W^X violation

Output of mount command:

/dev/sd1a on / type ffs (local, wxallowed)

Output of dmesg command:
