I see the 5 to 6 diagmond processes per minute on
an HP 3000/968 with:

  0) MPE/iX 7.0, C.39.06
  1) no users
  2) log type 111 enabled ... and NO entries
  3) no external devices
  4) two internal devices: one disk, one DDS
  5) proper SCSI termination (inside and outside)

I also see them in separate tests after:

  6) netcontrol stop & nscontrol stop
     (after the diags are initialized, of course)
     (and with network unplugged, in a separate test)

So...I/O errors (network or disk) don't seem to be
the culprit.


BTW, someone should look at diagmond and fix a bug / design
flaw.  It opens /var/stm/data/os_decode_xref **21 times**,
and /var/stm/data/monitor_paths 4 times!

It's also inefficent in loading and running because it's
using *13* libraries:

   /lib/libc.sl
   /lib/libsvipc.sl
   /usr/lib/libIO.sl
   /usr/lib/libmcats.sl
   /usr/lib/libsocket.sl
   /usr/sbin/stm/lib/libdiaggs.sl
   /usr/sbin/stm/lib/libdiagms.sl
   /usr/sbin/stm/lib/libdiagpl.sl
   /usr/sbin/stm/lib/libmpestm.sl
   /usr/sbin/stm/lib/libstmsec.sl
   /usr/sbin/stm/uut/lib/tllibio.sl
   /usr/sbin/stm/uut/lib/tlmisc.sl
   /usr/sbin/stm/uut/lib/tlpdc.sl

Note that those problems don't affect/cause the 5-per-minute
problem :)
