I got a large number of replies, that basically all said the same thing.
The solution, as for many of the NIS maps, is to make sure you have no blank
lines in the source file for that map.
(I had come across that problem with the netgroup map, but the blank line
caused things to fail consistently in that case.)
There were a couple reasons why I didn't think about such a simple solution.
First of all, the blank lines had been in my /etc/services file almost from
day 1, and the problem only showed up much later (likely when I upgraded
from 4.0.3 to 4.1.1). Also, since the problem was intermittent, I suspected
it was timing or load related.
I've made the fixes to my services map, and have yet to see if it cures the
problem. I'm confident it will, given the number of responses I got.
