Sometimes glance (performance monitor for HP-UX) can crash (before crash, it will return 0% of CPU, Disk and networking) working with the following error:
GlancePlus fatal error.

Connection to midaemon lost -- check midaemon process and status.mi == End of Error Msg
=============================

To solve it, you should:

Stop MWA:
# mwa stop

Remove all files (including the hidden ones) from /var/opt/perf/datafiles:
# rm -rf /var/opt/perf/datafiles/* rm -rf /var/opt/perf/datafiles/.*

Check if midaemon and ttd are stopped:
# mwa status

If midaemon and ttd didn’t stop, force stops them with the command kill (the PID was returned by the command ‘mwa status’).

Now, start MWA again:
# mwa start
