Subject [jira] Commented: (CONTINUUM-1353) after a few weeks, continuum runs into outofmemory error
Date Wed, 06 Feb 2008 06:49:29 GMT


tony nys commented on CONTINUUM-1353:

Currently we are using beta-4 in production.
Until now, we didn't have the problem.

Before the upgrade we used a workaround, a small sql program/script which regularly cleans
up the db.
This script can be run also from continuum.
In this way, the berkely db tables are cleaned up.
