Univention Bugzilla – Bug 39167
Increase default mdb maxsize
Last modified: 2020-11-18 16:43:53 CET
We should increase the default for ucr ldap/database/mdb/maxsize currently this is 2BG. "Set it to a few hundred GB" -- source http://www.openldap.org/lists/openldap-technical/201208/msg00177.html
2GB.. not 2BG :-) No BGs here.
This issue has been filled against UCS 4.1. The maintenance with bug and security fixes for UCS 4.1 has ended on 5st of April 2018. Customers still on UCS 4.1 are encouraged to update to UCS 4.3.

In this case please provide detailed information on how this issue is affecting you.
More and more larger customers are having issues with the default size. Customer had this issue shortly after using the system. It should be increased by default i.e. to the double size. And it should happen to all three databases! ucr set ldap/database/mdb/maxsize=4295000000 ucr set listener/cache/mdb/maxsize=4295000000 And translog database, too.
