rebuilding db on openldap 1.2.13 fails

[Jure Pecar <Jure.Pecar@select-tech.si>]

Hi list,

I have an openldap 1.2.13 running on a production redhat 6.2 system, 4way
smp and highmem on kernel 2.4.17. Openldap is linked against berkley db
2.7.7.  Because indexes get corrupted every now and then, i wrote some
scripts to do nightly database rebuilds. Recently, these started to fail;
output of the script cron sends me is 'id2entry ldbm_store failed' and
some of the resulting files are indeed smaller than the working set.

Any ideas on how to solve this? With google i found some references to
this back in openldap 1.0; i'd say these were fixed by 1.2.13 :) There's
plenty of diskspace left ... 
And i'd really need to rebuild again, as ldapsearch is again not returning
some users that are in db.
