whats wrong?

[Evil X]

why does it say this

threadviews Check Warning: 2 clients are using or haven't closed the table properly
threadviews Check Status: OK
threadviews Optimize Status: OK
upgradelog Check Status: OK
upgradelog Optimize Status: Table is already up to date
user Check Warning: 2 clients are using or haven't closed the table properly

^2 of the tables show problems
