Dear Luis Bernardo, I have to check if I share the Factory between threads - might be possible. Thanks for running the single thread test. In the meantime I have created a small test example - which should repoduce the problem - but it runs without producing the exception. So I will have a much deeper look at the problem and come back when I find out more. Greetings PowerStat

I ran an intense single threaded test that reuses the FopFactory and had no problem. If you are running single thread then send your PDF so that we can investigate.
