I am getting "Result too large" error while applying configuration changes; in fresh jenkins server setup with latest stable (642) as well as Beta (647) version with quite a big number of Plugin selected...

I am using Tomcat as web server.
When I tried to Configure Jenkins via Manage-Jenkins>>configure with required changes & clicked
Apply: I get error as "Result too large"
Save: I get same error as above
(if nothing changed & click Apply gets Blank error as shown in attached... )

with NO Stack trace or so to get any idea where something gone messy...

I feel, this might be problem with response received from server might be too outside data carrying capacity but with few tweaks like given in solution of "form to large" (request) as well as maxHttp* (response) setting changes in tomcat server.xml

BUT no luck...

Also noted that, if made any changes on configuration page; data gets saved till around half of the form but not later than that...
I also tried locating same error in BugTracker... but nothing found in same...

I did also tried removing quite a number of plugins keeping only required for-now to get rid of the error but no-luck there too...

Can you please help me out here...?

attaching error-snapshot

regards,

ps: since i am trying the most of the stuff on configure page which is located later half of the page which doesn;t get saved on click of Apply, hence marked it as Blocker...
