Does it say anything else?
Do you get an email with the error information?

what is the error above that line? there are no database changes so an upgrade is not going to fix the issue.

Try to run this sql query on your database
REPAIR TABLE smf_log_online;

If not we might have to rebuild/recreate that table.
