save failed

[Chris-42]

first thanks for the great work.

I faced a problem while executing save command. It doesn't write but throw errors like 'bus error' or 'segmentation fault'. The solution was to cleanup the /var/etc/persistent/data directory which seems to contain too much statistical data.

Thanks for reporting.
It might even make sense to completely disable the internal stats.

Feel free to create a documentation PR 😃
