[mrtg] minus one as a value

[Bob Van Cleef]

I'm trying to track vmstat stuff on a solaris box.  When I run mrtg
manually, I always get the correct values.  However, when run out of cron
(same userid) it often gets "-1" for values.  I've found no clues in the
docs or FAQs as to the meaning of "-1" in the log file.

Here is the top of the log when I run it...

993773127 4100408 581048
993773127 4100408 581048 4100408 581048
993772961 1 1 1 1
993772800 2200591 311930 4100512 581280
993772500 1886242 267368 4100536 581256
993772200 1 1 1 1
993771900 683679 97179 4102120 583128
993771600 1 1 1 1
993771300 1 1 1 1
993771000 1 1 1 1
993770700 1 1 1 1

Here is the top of the log a little bit later.

993773261 -1 -1
993773261 1 1 1 1
993773127 4100408 581048 4100408 581048
993773100 1899856 269219 4100408 581048
993772800 2200591 311930 4100512 581280
993772500 1886242 267368 4100536 581256
993772200 1 1 1 1
993771900 683679 97179 4102120 583128

Config details below.  I have tried playing with MaxBytes and
AbsMax, thinking that might be the issue, but no luck.
