why do I keep getting this error in the syslog of pmp100 AP?

File ../src/webportglu.c : Line 574 :Internal Error, we are out of file space?! temp57714.html

The file system on the AP is out of space.  Ideally, this should never happen.

Most likely it is due to the fact that the file system on the radio is corrupted. Our recommendation would be to do a factory default, reboot and then rerun to see if every things comes back normally without any errors.
