Hello,
I have a problem with gmetad segfaulting. I'm running ganglia version 3.0.3 on
RHEL4 update 4 (AMD x86_64). The error looks like this (from
/var/log/messages):
=====================================
__/cpu_system.rrd): illegal attempt to update using time 1199966992 when last
update time is 1199966993 (minimum one second step)

========================================
Note that there are a number of other errors but these also appear in a
parrallel envinronment that is running fine (except the errors!).
My rrd repository just edged over 2GB:
none 4194304 2102852 2091452 51% /var/lib/ganglia
Is this a problem? I created a fresh rrd area, changed rrd_rootdir (in
gmetad.conf) to point to the new area, restarted gmetad and gmetad doesn't
segfault and writes to the new area - but I don't have my performance history.
Any help will be appreciated.
Thanks
