[Hippo-cms7-user] CMS locks down completely after a modest load test

Hi all,

-------------
Introduction:
-------------

In our acceptance environment we have encountered a bug where the CMS locks
down completely after running with ~5 actual concurrent human users.
In order to narrow down and reproduce this issue, we have taken your
quickstart version of the CMS 2.09.04, and applied a simple automated load
test
with which we were able to reproduce the issue.

--------------------------
Reproduction of the issue:
--------------------------

We followed the instructions on:

http://www.onehippo.org/cms7/documentation/quickstart.html

and downloaded the quickstart from here:

http://repository.hippocms.org/maven2/org/hippoecm/hippo-ecm-quickstart-bin/2.09.04/hippo-ecm-quickstart-bin-2.09.04.zip

Without further modifications, we started the CMS quickstart on a developer
notebook.

We used a load testing tool called "Pure Load" (trial version) that allows
recording and replaying of http requests.
See: http://www.minq.se/products/pureload/

As such, we set up our test to simulate 5 concurrent clients that perform
the following steps for an infinite amount of time.
Note that the scenario below was run from a simple notebook as well.

- login to the cms under unique user credentials
- navigate to the news folder
- create a new newsitem with a unique name (counting up)
- save the newsitem (including 'done', and closing tab)
- navigate back to the document root
- log out of the cms

Results:

After running this test setup for 5 to 10 minutes we observe that requests
from the load tool no longer are served.
Trying to login to the CMS from a browser with no running session (clear
cache) results in a timeout: the login form does show, login times out...

Users with a running session in the CMS, are capable of navigating through
the CMS without visible issues.
Logging out such a user, will result in a timeout, trying to logout.

--------------------------
Further information:
--------------------------
See attachments.

- Deployment: clean Hippo 7.2 (2.09.04)
- Tool: PureLoad (free edition, trial version)
- Test Script: see attachment
- Nr of workers: 5 (logical names: scenario0 ... scenario4)
- Nr of threads: 5 (one per worker)

The script uses five (admin)users in the CMS:
- dennis0 / dennis0
- dennis1 / dennis1
- dennis2 / dennis2
- dennis3 / dennis3
- dennis4 / dennis4

We used a 6th user (just admin/admin) to monitor activity in the CMS while
performing the test.

We are sure you can help us out.
If you need any more information, let us know.
