So your DSIZE is limited to 512 MB (hard limit).  How
big does your milter-greylist process get?  It is quite
possible that you're hitting the limit.

If that's the case, try increasing the hard limit (it's
a kernel variable that can be changed statically in the
kernel config, or changed via a loader tunable).

The following two lines in your /boot/loader.conf file
will set both hard and soft limits for the data segment
size to 1 GB:

kern.maxdsiz="1073741824"
kern.dfldsiz="1073741824"

Best regards
