Dear managers,
we experienced crash twice in less than 48h. The crash data look similar.
I can suppose it's a well known error which is already fixed in the
system. The current process is Xdec.
It's important to notice that in the second case nobody was logged from
the console, we have DEC 2000 model 300, version 3.2c + enhanced security.
Following is a fragment from the crash-data file.
I'm anxious also: couldn't it be a form of an attack? And what does "Invalid
character in input" mean in this case?
Thanks,
Irene
