XForms - External instance XML data size limit? 64K?

Hi,

While trying to understand why repeat seems to cause a "memory leak" I 
stumbled on the following situation illustrated in this WAR:

I'm using

<xf:submission id="__get_schedule" 
action="http://localhost:8080/XFSchMgr/XMLData"
method="post" ref="instance('__schedule_selector')"
replace="instance" instance="__schedule" />

to retrieve external instance data. Data is a mock schedule randomly 
generated by the attached servlet and I tried to retrieve several days 
of it.

I can retrieve 5 days worth of "schedule data" (roughly 64000 bytes) but 
I get an xforms-submit-error for 6 days (roughly 78000 bytes).

Is there a limitation on the size of the external instance data?



To reproduce: deploy the war (I tested on Tomcat v5.5 with J2SE 1.5), 
point the browser to http://localhost:8080/XFIssues/xmlSizeLimit.xhtml 
and click the button. Then edit the HTML file to retrieve 5 days instead 
on 6 and try again. The servlet would write the XML size to System.out.
