[comp.sys.ti.explorer] hanging up on file accesses

gbyrd@mcnc.org (Gregory T. Byrd) (11/16/90)

I have a microExplorer system with one internal and
two external Apple 80MB hard disks.  The machine occasionally
gets into a "hung" state when opening or closing a file.
It usually, but not always, happens when doing a lot of
consecutive file operations, as in a make-system.

The symptoms:

1. The status line says "open" or "close," and there is no
   disk activity or run bar activity.

2. I can get the machine back by aborting the access, but no
   subsequent access works.  (Always hangs in the "open"
   state.)

3. A warm boot gets things working again.

I wondered if there was a problem with the SCSI termination, 
but I've tried placing the terminator at different points in
the change with no noticeable effect.

Also, the last time this happened, I was able to access the
same disk and files from the Mac with no problem.

I'm running system 6.15 with microcode 138.

I've seen the problem with hangs when writing files on an mX from time to
time (though rarely) and always felt it was due to bugs in the microExplorer
application's NFS or RPC code, though I could never prove this.
Unfortunately, I was never able to find a work around for the problem either,
though sometimes I was able to get to the cold load stream to save files.
