ReadyNAS RN212: System volume tmpfs's usage is 100%

[thadanders]

Hi,

Ever since I enabled the cloud service Microsoft OneDrive on my ReadyNAS RN212, every day I get the warning "System volume tmpfs's usage is n%. This condition should not occur under normal conditions. Contact technical support." (n is 90-100%).  How should I take care of this?  The culprit seems to be the file "/run/readydrop/MCIPC0MBSJL-myStuff.echo" which is size 1009 GB.  "MCIPC0MBSJL-myStuff" is the name of one of my ReadyCloud "Backup PC" folders.

Thanks in advance for your consideration!
