Clean up error.

RouterOS Beginner Basics

Hey there guys,
I got this error in the logs:

nov/22 01:56:32 manager,error,info,debug failed to cleanup session.acctSessionId: unable to open
    database file
nov/22 01:56:32 manager,error,info,debug failed to cleanup log.acctSessionId: unable to open database
    file

I also cannot perform a check-disk, nor there are any (none!) files in the Winbox\files grid.
I tried to reboot and I couldn’t (from Winbox and SSH console) and I am now reluctant to go and do it by keyboard.

Any ideas?
Disk is 99% free as said in Winbox\Files.

I had these same symptoms. Try doing a hard drive fitness test.
