I'm seeing gaps in some charts and not in others. The charts for vmstat tcp ifstat show no gaps. All of the other charts show consistent gaps of several hours, followed by a brief period of data, followed by more multi-hour data gaps.

After appending --debug to the rrd_data line in tasks.cfg, tailing rrd-data.log shows many messages of the form: "Peer not up, flushing message queue" and several messages of the form: "Child process 10502 died: Signal 6"

This makes me think some portion of the rrd listening process is crashing, leaving gaps in my data.

Can anyone suggest how to determine why the rrd is dying?

Could the absence of gaps in the previously mentioned charts be because they are being populated by rrd_status rather than rrd_data?
