Your flash can be full with either crash files, logs or you might have loaded firmware files and saved it to flash.
Check "dir flash://" and "show service crash-info" and delete what's not needed.

Hello Ismael,

please check following article:

How to remove crash files from WiNG device?

Also, check if there are some extra upgrade files in controller’s memory
dir flash:/upgrade/

That would mean you have manually uploaded firmware packages in RFS’s memory.

Remove those with delete command

delete flash:/upgrade/x.img
Then you can check system memory status with following commands
service show mem
service show sysinfo
