[mrtg] Re: daemon robustness problem

[Jason Frisvold]

I have 4 more .rrd files that are bad if you want me to send them to
you...  (The actual .rrd file this time, not just an xml dump)

Let's do an inventory.  Who's having these problems and what
(version of) software are you running.

OS
MRTG
RRDtool

and, last but not least, what scripts are used for, for instance,
"spike removal".

Maybe we can spot a pattern.

I've loosly analised the output of rrdtool info on one of these faulty
.rrd files and it looks as if stat_head is overwritten with garbage.
Not only the CF was wrong, other parts were also wrong.  I can't
remember
exactly what it was however one of the numbers was replaced by four
ascii
characters.  That is just too unlikely to be coincidence.

I'd welcome a chance to look at a damaged .rrd file.  Please make one
available if you have

cheers,
