Hi,

        One of our Apollos (a DN4500, Sr10.2) has developed the habit
of slowing down so much, that it becames unusable. This behaviour seems
to start out of the blue. Sometimes the users manage to logout, but
it is usually impossible to login again: when you type the username
the station locks up. Hitting the return key seems to have no effect.
Using the backspace key causes some black squares to appear on
the DM window, but no backspacing.

        During one of the last fits, the user tried to logout. After some
time, he got the (almost) usual question (Blast ? (Y/N)). After answering
Yes and waiting some time, the message  'Unable to obtain scfb hash table mutex
lock from (stream manager/ scfb)' ?

        What does this message mean?
        What might be wrong ?

                Any ideas, hints, etc..,  welcome


                                Thanks,
                                Joao C Ferreira
