I keep getting Bus Errors continuously. Some examples how to get them:
- Running systat -swap will over short or long give a line
like 'Error in kvm_read: Bad Address', and a little bit later, there
will be either a segmentation fault with core dump or a bus error.
This sympthom seems independent of system activity, swap space
usage and the likes. Also, the time upto how long systat runs _without_ crashing varies from some minutes to some hours.
- Running some configure scripts also causes Bus errors, especially
during the perl5.001
Configure script, output was somewhat like
'Looking for xyz - not found'
'Bus Error - Core dumped',
even if the specified program is present.
The program causing the Bus Errors in this
case seems to be sh.
- NetScape from time to time produces Bus Errors , too.
E.g. I simply start it, do
something else on another computer, and when I
return and move the mouse-pointer back over
netscape's window, netscape quits with a Bus Error and a core dump.
check the routines used e.g. by systat and have a closer look at the associated kernel routines.
