Well, I would have liked to know the truth, such as

ERROR: short write on block blah
DETAIL: wrote %u bytes, %u requested
HINT: That might mean that the disk is full.

In our instance, there is no fullness problem.  (The errors repeat too 
inconsistently yet persistently for that.)  Probably, the storage 
device is improperly mounted (which could become the second half of the 
hint), but I have to wait for test results.
