Package: collectd Version: 4.4.2-3 Severity: normal A system I have collectd installed on, and sending to a remote collectd server via the network plugin, was taken offline, and was rebooted in that state. An excerpt of the log after the reboot:

Please load at least one plugin that provides a write function. collectd continued to log the same line, several dozen times in a row, every 10 seconds while the network was down. This resulted in some 500 mb of log files being written to disk. With a longer network downtime and a smaller disk, this would fill the disk. I suggest collectd be fixed to log only once. Further, once the network came back up, collectd did not notice and continued to fail. Looks like the network plugin failed once at the beginning, and did not retry connecting? Surely it should retry occasionally? -- see shy jo
