Collectd and RRDTool keeping shares from network

My TrueNAS server putting out the following code all day long:

…collectd 1675 - - rrdtool plugin: queue thread: Wrote 1 value to …/cpu-user .rrd
…collectd 1675 - - plugin: plugin_write: Writing values via rrdtool

I don’t know what the above means. I cannot access neither of my two datasets via SMB Windows Shares and “dataset1” is full but I cannot access it to free up some space. Do I leave this running until it’s finished and will it be finished? What steps should I take if this is not a common occurrence?
