Either there is an mbuf leak somewhere or the driver hits its own limit for mbuf clusters (I don't have the source here and I'm going to leave for two days). As I remember the proatm driver has a configurable limit on mbufs. F>Now I must go back to FreeBSD 5.1 and ForeRunner with idt driver - this is F>not stable but work.

As every non-paid open source project FreeBSD is developed by volunteers. If someone finds a problem and helps the developer to get the problem solved things will get better with time. I have asked you for panic message and stack trace. These are really simple to get. How do you expect I'm going to fix your problem if you're not going to help me fixing it? harti -- harti brandt, http://www.fokus.fraunhofer.de/research/cc/cats/employees/hartmut.brandt/private brandt@fokus.fraunhofer.de, harti@freebsd.org
