You are running Adobe LiveCycle 8.x, 9.x or 10.x on Solaris 10. When you apply Update 10 to Solaris, forms will no longer convert properly through LiveCycle Output and you will see an error similar to the following in your application server log:
####<Jan 1, 2012 12:00:00 AM EST> <Error> <com.adobe.formServer.PA.XMLFormAgentWrapper> <t0q22k><ServerName> <[ACTIVE] ExecuteThread: '1' for queue: 'weblogic.kernel.Default (self-tuning)'> <<anonymous>><BEA1-1DE0F90E6C7CBD70F8FA> <> <1326470773795> <BEA-000000> <ALC-OUT-002-004: Unable to findservice: XMLFormService, error: Connection to failed service.>

There is an interaction issue between the compiler settings that Adobe uses to compile the XMLFormService and some additions that Oracle have made to Solaris to support GNU extensions to their ELF symbol versioning. What this means is that Solaris no longer recognizes XMLFormService as a valid executable and will not run it.
