Sorry for the cross-post but this relates to both lists.
Hi All
==SYSTEM==
DSpace 3.2, Ubuntu 12.04 LTS.
==Problem==
Our recent upgrade revealed some serious system stability problems.
1. We had to set the "maxHttpHeaderSize" parameter for Tomcat 6, when using
Tomcat without the Apache "mod_jk" module.
2. We had to delete some old tables in the PostgreSQL DB relating to the
conversion of the browse indexes to the SOLR DB.
We run one of the larger repositories with 55,000 records and about 10,000
full text items.
We also have a large admin and normal user base after two years operation.
So although the demo DSpace website may work, things change radically in
production environments, when doing version upgrades, not fresh installs,
and having many records and users.
==Possible Solution==
The Debian Linux distribution has a solution for always maintaining a
stable version of software.
They have an unstable, testing and stable repository of software.
All new items land in unstable.
When the new items are then tested and if proved working, then they are
moved to the testing repository.
The items stay in the testing repository until all bugs have been revealed
and removed.
Then items in testing move to the stable repository.
This could suit DSpace very well.
Those institutions that do not employ a full technology support stack,
could then safely run the stable version of DSpace.
Those institutions that have a full technology support stack could then run
testing and help to get new software into unstable.
This would also help libraries in developing nations that do not normally
have a full technology stack of expertise at their disposal to run the
latest "stable" version of DSpace.
==Possible Action==
Perhaps a resolution could be made to Duraspace community management to
change to such a release process.
This would allow new features to land in DSpace safely after being
throughly tried and tested in large production environments.
