  I've had problems with milter for my own greylist implementation [1] which
I suspect has to do with stack space.  Milter creates a bunch of threads,
and at least under Cent-OS (which we use at work), uses about 10M per stack
per thread.  Currently, I explicitely set the stack limit (using the system
call setrlimit(); also doable from the command line via ulimit) to a smaller
value and that seems to have helped.

  -spc (How small?  Try 128k stack limit)
