java.net.SocketException: Broken pipe

Description of problem:
Sometimes, you can get a very confusing exception in the server log, that doesn't seem to correspond with any failure visible in the GUI:

ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[default-host].[/business-central].[ErraiServlet]] .. JBWEB000236: Servlet.service() for servlet ErraiServlet threw exception: javax.enterprise.event.ObserverException
..
Caused by: ClientAbortException: java.net.SocketException: Broken pipe
..
Caused by: java.net.SocketException: Broken pipe

If there actually was a problem and some admin had to go through the server log looking for the cause, this would make the task so much harder for him.

You can get this e.g. by going to Project Authoring perspective and refreshing the page while it is still loading. (Such a scenario is quite probable if you have a lot of assets and the loading takes too long.)

Version-Release number of selected component (if applicable):
BPMS 6.0 ER3

How reproducible:
1/3 to 1/2 of tries

Steps to Reproduce:
1. Get a bigger git repository.
2. Go to Project Authoring perspective.
3. Refresh the page while the perspective is still loading.
4. Look into the server log.

Actual results:
java.net.SocketException: Broken pipe stacktrace.

Expected results:
No error.
