I'm going to first try manually copying stuff to confirm that DB>this is the problem and then try m_pullup followed by m_adj. m_adj should work on any mbuf whether with a cluster or not given that you mbuf is setup correctly. Where do you see a dependence on not beeing a cluster in that code? harti -- harti brandt, http://www.fokus.fraunhofer.de/research/cc/cats/employees/hartmut.brandt/private brandt@fokus.fraunhofer.de, harti@freebsd.org
