Hello,

We installed UBB Thread in Linux CentOS a few years back. Now I ran into an issue "iNode is full". This issue is because of "httpdocs/ubbthread/session" folder has twenty-three million files. Can I clear those files will it cause any issues? Please help me with this.

UBB Message(User): We encountered a problem. The reason reported was
Database error only visible to forum administrators

Thanks in advance for your help.

Ensure that garbage collection on your system is occurring at least every 30 days on the sessions folder. There's not really a reason why people need to be logged in more than 30 days.

PHP should by default Purge garbage files on a set schedule.
