Thanks Rupert and Fabian for your responses.

Hi Rupert,

Thanks for suggesting workarounds.

We have tried all three workarounds but the issue persists. I am sure i am
missing something, if you can please review below findings will help us
identify gaps in our approach.
*
*
*"1. reduce the size of the configuration (e.g. by removing comment
lines from the field mappings)"*

We are configuring EntityHubLinking engine and we dont see any comments as
it is present while configuring ReferenceSite.

*"2. configure the Site using the configuration file located in
"stanbol/fileinstall". Make sure that changes to the file confirm to
the syntax required by the *.config files"
*

We tried configuring EntityHubLinking engine by editing "*
org.apache.stanbol.enhancer.engines.entityhublinking.EntityhubLinkingEngine.org.apache.stanbol.enhancer.engines.entityhublinking.EntityhubLinkingEngine.f7141185-9fe8-4ab9-ad05-fa4988399694
.config" *file located under "*stanbol/fileinstall*" folder. We added
fields value under "*enhancer.engines.linking.dereferenceFields*"*  *property.
But this didn't result in we getting more information for additional fields
in derefrenced entities.

Do i need to restart stanbol server after editing *.config files ?
The catch here is on our OS, felix configurations doesnt persist after
restarting stanbol.

*"3. running Stanbol as WAR within a Tomcat. In Tomcat you can configure
the headerBufferSize like explained in [3]"
*

We added stanbol.war to tomcat, however it is throwing an exception on
opening Felix console. Following is exception stack trace
