It looks like the overhaul of getpwent Apr/2003 to make it thread safe:
http://www.freebsd.org/cgi/cvsweb.cgi/src/lib/libc/gen/getpwent.c
may be the problem.
I've tested the dbm_fetch function independently on a large
file, and it is fine.
I've opened a bug report, and plan to build a replacement 4.x
mail server, as the most deterministic path to restoring
adequate e-mail service to our users.
Can anyone suggest a workaround ?
