Indeed it was vsz_limit. I set it to zero (under service lmtp) and now the script works.

However I’m noticing a couple things:

1) I previously had the vsz_limit unset, and subsequently set to 256M; neither worked.

2) I wrote a test script that just ran in a loop appending to a string and printing to stderr how long the string was; it was killed after it reported accumulating about 2MB.

Weird? or normal?
