Since upgrading our openldap (v1.2.13) server to 4.8-STABLE from 4.7-STABLE,
we've noticed that the slapd server increasingly eats up memory, before
dieing and coredumping after about 15 minutes. I rebuilt the package (via
ports), post-upgrade, to see if that fixed the problem and no dice. I've
rebuilt libc_r and the pkg with debugging symbols, yielding the following:
# gdb ./slapd.static ./slapd.core
<...snip...>
Core was generated by `slapd'.
Program terminated with signal 11, Segmentation fault.
