I have recently started to get a strange
message appearing in the error window for the DM.
It is something like:
unable to get sfbc hash table mutex lock
Does anyone know what is causing this
and more importantly, how can I stop it from
happening again.
for the record we are running 9.7 on 3000's
Thanks

This is a generally fatal bug. If you see it, you should reboot right away as things are not likely to get better. In short, something has grabbed but failed to release a critical system mutual exclusion lock (in this case one that is needed every time a file is opened). Unfortunately, in my experience this bug shows up only very sporadically and it not generally reproducible. Needless to say, however, if you continue to see it, you should file an APR. -- -- Nat Mishkin Apollo Computer Inc., Chelmsford, MA mishkin@apollo.com

I've seen similar messages after users have been blasting processes on their nodes to force them to stop. The manual states that the node should be rebooted after blasting a process. We have a sys. admin. here that use to blast processes regularly without rebooting. After a while, some of these machines started to act real sluggish and not execute the ~user_data/startup files correctly along with others problems. After several hints from me and finally one offical reply from Apollo support, she changed her way and followed the recommended reboot and are nodes lived happily ever after. -- James Kwong Calif.
