Those were the last 2 lines on the console before the hang.  There is nothing at all in messages about this.  I suspect the system was not totally hung, just the etnernet interfaces (2 different ones) as I could still ping both interfaces successfully.  However, no attempt to access any service worked.

There are em0 and dc0 ethernet interfaces.  This is almost a generic kernel.  The config file contains:

I have no ATM interfaces so it shouldn't be loading to my way of thinking.

Nothing.

kldstat -v shows:

if_en is not listed as compiled into the kernel.

The kernel and userland were built shortly after an install from memstick image using the procedure in UPDATING:

        To rebuild everything and install it on the current system.
        -----------------------------------------------------------
        # Note: sometimes if you are running current you gotta do more than
        # is listed here if you are upgrading from a really old current.

        <make sure you have good level 0 dumps>
        make buildworld
        make kernel KERNCONF=YOUR_KERNEL_HERE
                                                        [1]
        <reboot in single user>                         [3]
        mergemaster -p                                  [5]
        make installworld
        mergemaster -i                                  [4]
        make delete-old                                 [6]
        <reboot>


After that the ports and application software were installed.  Basically the only services that run on this system are nagios and mrtg.  It is used only as a monitoring system for my production server and for testing new software.  It has only been used for monitoring since the upgrade.  I can't do any development work till I get the production servers upgraded from 8.2 to 9.0.

When this repeats I will do that.  Thanks for the help.
