In Amanda 3.5, the "/var/log/amanda/<CONFIG>/amdump" path is actually
just a symlink pointing to the currently-active amdump file among the multiple
timestamped files (amdump.YYYYMMDDhhmmss), so the original log file should
still be out there.

It will be interesting to compare the contents of the logs from working
and non-working runs.  So:

1) what's the timestamp for the run that generated this error?

2) what does 
     $ grep SHM-WRITE amdump.202012[12]*
   show (when run from within the correct .../log/amanda/... directory)?  

   (The idea being to grep through all the amdump.* files from the past
   13 days, just as a quick way to hit both good and bad runs.)

3) is there any correlation between the runs where amstatus returns this
   error and other interesting messages appearing in the Amanda Mail
   Report for those runs?
