PHP Session Issues

There was no problem, today suddenly the server session suddenly useless. Cross interface does not take session ... Refresh Page The session is gone ... There was no problem before, and no action was done. What's the reason?

is to do a video upload platform with an open source project.
Servers are lighttpd and Nodejs

Thank you.

Thank you.

• See if the hard disk space is full.

• Check php.ini to see if it's session.auto_start turned on

• Did someone change the project? See session if it's manually closed?

• Not to rule out the possibility of being attacked.

I haven't done any of these projects.
