Incorrect key file for table ‘./conntrack/2016@002d12@002d16.MYI’; try to repair it

If you see the above error while accessing Connection Tracking Reports in Radius Manager then …

Recommendations:

  • Make sure you aave plenty of Disk Space. Storage drive should be fast for high load servers preferably SSD or RAID based storage ,
  • Plenty of Memory is usually a good idea for DB systems ,
  • If its a heavy production server, try to move connection tracking to separate host as it takes lots of space and it adds good amount of payload to the CPU as well.
  • Perform tuning to enhance the mysql engine

To repair table …

Goto the conntrack folder [Ubuntu]
cd /var/lib/mysql/conntrack/
service mysql stop
# Change the file number as shown in the error 
myisamchk -r -v -f 2016@002d12@002d16.MYI

Once repair is done, start mysql / restart apache2 services , and test the desired tracking report again.
