ITS#1986 question "cache add failed" on OpenLDAP 2.0.25

[Jan-Michael Ong <jmong@adobe.com>]

Hi we're using DB 3.3.11 and OpenLDAP 2.0.25 and only recently we've been 
getting the following errors but defining a "database ldbm"

LDAP: error code 80 - cache add failed

I've come across this answer from Howard Chu but couldn't find any 
reasonable follow ups..

http://www.openldap.org/lists/openldap-bugs/200208/msg00117.html

Is this "fixed" on 2.0.27? If not, does anyone have any idea what's causing 
it (i.e. permissions on the file system? the db couldn't handle it? is it 
because the ldbm is being corrupted somehow?)

Any help will be greatly appreciated.

Regards,
