Hi,
yesterday we found that the RDBDocumentStore in Oak 1.2.11 has a bug
which will cause entries in the "journal" collection to continuously
grow, eventually causing OutOfMemory errors.
The bug is fixed now (see
<https://issues.apache.org/jira/browse/OAK-4021> and
<http://svn.apache.org/viewvc?view=revision&revision=r1730583>). People
running Oak on RDB who aren't yet on 1.2.11 are advised to wait for
1.2.12, due to be out in a few weeks. People running Oak on RDB who
*are* on 1.2.11 already are advised to apply the patch mentioned above.
Best regards, Julian
