Henrik,

disk is generate by netapp.pl (from the hobbit-client-perl)
-> i noticed that in my 3 extracts, the last log before the crash is disabled. Looks like this could be a problem ? (i've check 2 other crashes, and there again, the last log is a disabled status)
i checked those 3 disabled status : those hosts are up and running (so normal status are sent to hobbitd) we have disabled them for migration purpose, that might happen in a few days, or weeks... 




For your mysql question :
yes i do graph mysql using NVC
NCV_mysql="Questions:DERIVE,Threadsconnected:GAUGE,*:NONE"

It happened again today at 17:00:22.
Nothing new when doing a bt on the coredump.
An extract of rrd-status.log from 16h55 to 17h05 is available at http://www.qalpit.com/~olivier/tmp/rrd-status.log.gz 

OK, the interesting part is here when it crashes:

It appears to be a "mysql" status from either cedratnet-bdd1 or nurun-etam-bdd1 that causes the crash (I cannot tell exactly, because output buffering comes 
into play when there's a crash). It *could* also be the cpu-report from
moniteur-ora2, but I doubt that - the cpu-status is tested a lot more than the mysql-status. 

In fact, "mysql" isn't part of hobbitd_rrd by default. So is this something
you've added ? Is it something that you generate graphs for ? Or is it just
a status that hobbitd_rrd should ignore ?

Henrik
