Thank you for your help with my last question. Maybe you can all help me
out again now.
We have been having a lot of crashes with an ADVFS EXCEPTION panic N1 = 5.
It eventually turns out that is a file (or maybe files) on one of our advfs
filesets which cause these crashes when you try to "rm" them. We will be
doing some more experiments this evening (when the system is less loaded
and crashes will inconvenience less people). I have three questions:
1. how do we delete these files and stop the crashes?
2. how do we detect other files that may have similar problems?
3. how do we prevent these problems from occuring in the future?
any answers gratefully accepted.
some extracts from the Crash-Data for the last crash are included if they
are any use. I have looked in the archives, and tried the msfsck/vchkdir
solution but that was no use.
thanks in advance,
clare
