What version of the product are you using? On what operating system?
Jars are 
  de.huxhorn.lilith.3rdparty.flyingsaucer.core-renderer-8Pre2.jar
  htmlcleaner-2.2.jar

Running on windows XP

Please provide any additional information below.

The table generated by YUI is causing the problem I'm sure because if I remove 
all the contents of the div <div class="box_bd"> line 362 in attached html the 
PDF is generated fine.

Need urgent help.
Thanks in advance!!

Ok found & resolved the issue. There was a problem with the HTML where an extra 
thead tag was generated  by YUI to handle column sorting
