False disk alerts.

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)

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.

Note the "]" character in the middle of "1K-b]ocks". This is reminiscent of a bug that was apparently closed in 4.3.0 (see http://lists.xymon.com/archive/2011-March/030833.html). What version are you running? On 22 September 2015 at 18:55, Neil Simmonds <user-feff97fabd3d@xymon.invalid>

Hi Jeremy, we're running 4.3.4 but it's funny you should mention that bug as I have found some log messages this morning that say, BUG: splitmsg_done() was not called on previous message - data corruption possible. These occur at the times that we get the false alerts. Regards, Neil. On Tue, Sep 22, 2015 at 10:30 AM, Jeremy Laidman <user-71895fb2e44c@xymon.invalid>
