[Xymon] False disk alerts.

[Neil Simmonds]

Hi all,
We are having a strange issue on one of our Xymon systems. Occasionally the
disk alert flags but it is due to a malformation of the data. The alert
looks like this,

red Tue Sep 22 01:57:24 2015 - Filesystems NOT ok &red 1K-b]ocks (1 units
free) has reached the PANIC level (524288 units) &red C (0 units free) has
reached the PANIC level (524288 units)



Filesystem

 1K-b]ocks     Used       Avail    Capacity   Total Size   Free Space
Type    Mount Point

C             71114748   16071904   55042844    22%         67.82 GB
52.49 GB   FIXED   N/A

but if I then go to the history and then look at the client data it's fine.

I've checked to see if there are any strange invisible characters in the
client data but can't see any yet we're getting this peculiar alert.

Server is Linux running Xymon 4.3.4 (same as our other server) and client
is BBWin 0.13.

We have the same combination of client/server versions running on our other
system and have never had anything like this that I am aware of.
