Hi,

I have a complex infopath form that fails with an "Unknown error" when I try
to upload to Forms services. This uploaded on one server but failed on the
other server. I looked at the log file in web server extension folder and
below is the error i found. Can you please give me some input on what is
happening here and why it is failing. The server has 2 CPUs 2.2Ghz and 3.51
GB RAM.
