I've done some more digging.
The real bug is in nss_ldap. The current FreeBSD port is of a 2 year old
version and from
comments in the changelog in the current version of nss_ldap this bug is
known and fixed.
[the bug has been found before - as I understand it, nss_ldap doesn't mask
signals correctly,
and if the connection to the server has closed a SIGPIPE error is generated.
nss_ldap masks,
but doesn't ignore this signal and so continues on, but when the signal is
unmasked the cron
(or whatever) process gets the signal. D'oh!].
Unfortunately the current nss_ldap version (239 vs 204 in FreeBSD ports)
cannot be compiled
by the ports harness "as-is" as there are changes to the patched files -
there also appears to
be a bug in the Makefile.in for this version. I'm seeing if I can come up
with some revised
patches for this port to get it to build.
