Java allocates its heap via mmap(MAP_ANON) -- increasing the data segment size does the opposite of what you would expect, reserving address space that won't be used by mmap(), and causing the above failure. See vm/vm_mmap.c vm_mmap() -- From my cursory reading, mappings' 'start address' is set after the end of the largest possible heap (RLIMIT_DATA). Try dropping RLIMIT_DATA back to 512Mb. -landonf --Apple-Mail-2-381654693 content-type: application/pgp-signature; x-mac-type=70674453; name=PGP.sig content-description: This is a digitally signed message part content-disposition: inline; filename=PGP.sig content-transfer-encoding: 7bit -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (Darwin) iD8DBQFGXcx9lplZCE/15mMRAhcCAJoDSsUg/DEcbwLllT8/5q0J95LCwQCeOaZE kMnSnyqdUcwISJ8+w5EEgUU= =+k5R -----END PGP SIGNATURE----- --Apple-Mail-2-381654693--
