ERROR - Internal error cloning object

[Dipu Seminlal <di...@googlemail.com>]

Hi Igor/Eelco and Others,

Sorry i am reposting this, can any one please tell me how to get around this
issue.

I am seeing loads of "Internal error cloning object" error in the log files.
I am running on DEPLOYMENT mode and also  i have set
get().getDebugSettings()
.setSerializeSessionAttributes(false);
( which is not really required when i am on Deployment mode ) in the
application class.

I have an Iframe on different site pointing to my application like this
<iframe id="framename" name="framename" marginwidth="0" marginheight="0"
hspace="0" vspace="0" target="_top"
src="
http://sagittarius:8080/fab1gui/search?wicket:bookmarkablePage=:com.xmltravel.fab1.wicket.flights.HorizontalSearchNavPage"
allowtransparency="true" frameborder="0" height="210" scrolling="no"
width="540"></iframe>

I tried to simulate this situation and noticed that when i do a submit on
the Iframe for the first time this error is thrown.

How can i get around this issue.

My client has configured a spider to do searches on the live site and i am
seeing loads and loads of Internal error cloning object exception.
And worst of all today there was an out of memory error, i am wondering if
the repeated occurrence of cloning excpetion has got anything to
do with the out of memory error.

Regards
Dipu
