Twice since Monday I have had an EE install website go down because of a corrupted database table. The offending table has been exp_online_users both time. This site does not use public member logins, so only site administrators have access. Any idea what could be causing the table to become corrupt?
EE install version: v2.1.3 Build: 20110411
Any recommendations aside from upgrade to the most recent version? This site has been in use for almost 2 years and this is only a recent problem.
