Volume error on readynas 4220

Dear,

I just received an error

"System volume tmpfs's usage is 89%. This condition should not occur under normal conditions. Contact technical support."

 

Logged with ssh i found

root@nas-4220-1:/run# df -h
Filesystem      Size  Used Avail Use% Mounted on
udev             10M  4.0K   10M   1% /dev
/dev/md0        4.0G  1.5G  2.2G  42% /

tmpfs           3.9G  3.4G  457M  89% /run

directory is filled with a lot of files  export_db_background.xxxxx. More than 800000 with each 866 bytes

Running midnight commander show me the following files and size according the picture

 

Any ideas for the existence of such export_db files ?

 

Thanks in advance for your support

    Not sure where those files are coming from.  

     

    But I am wondering if you have tried rebooting the NAS?  tmpfs is a temporary file system (like a ramdisk, but it can be swapped out).

      Thanks for the info

      I carefuly moved these files to a temp directory and partition space recovered to something normal.

      I still do not understand why these files were created.

      I will continue to check in the folliwing days.
