Size limit for xforms/xml instances?

K.Linke
Hi,

I'm wondering if there is any known limit to the size of the xforms document and the xml instance document Orbeon can handle. I'm using a generated xforms document that is about 750 kBytes and an enlarging xml instance document. Everything works fine, but if the xml instance reaches about 150 kBytes I'm getting the following error:

I'm using Orbeon Forms 3.6.0.200712061930 as separate deployment on a Tomcat 5.5 with 128 MBytes heap space on my local test system. I tried to increase the heap space up to 1024 MBytes, but that doesn't help. Any ideas?

Re: Size limit for xforms/xml instances?

Hank Ratzesberger

There are some defined limits in resources/config/properties.xml
such as max-upload-size, however, your problem appears to be the
Java runtime.  Take a look at the recommendations for heap and
stack when you start your server:

Cheers,
Hank

How large is your Java heap? Set it to 256 MB or 512 MB.
