Error instalation nodes for modbus or OPC-UA

Hi, Recently I have been trying to install new nodes on node-red and usually give me this error, can someone help me solve it? I have very few things installed in the PLC and I find it strange to be out of space, thank you.

Hello, What is the result of the df command? If the Use% of the filesytem mounted on /media/rfs/rw is close to 100, then the memory is full. You can check the largest files using something like this command:

du -a /opt/plcnext | sort -n -r | head -n 20

Hope this helps. ~ Martin.
