Sometimes my clients site is down and it shows one of the following errors (black text on white screen):
[error] [system.db.CDbCommand] CDbCommand::fetchAll() fout: SQLSTATE[HY000]: General error: 1 Can't create/write to file '/tmp/#sql_135b_0.MYI'
CDbCommand faalde tijdens het uitvoeren van volgend SQL statement: SQLSTATE[42S02]: Base table or view not found: 1146 Table 'krycer_be_craft.t' doesn't exist
They are the same errors that are shown in the log files (with a bunch of other stuff). The wierd thing is, it doesn't happen all the time. Nothing changed on the site scince a few weeks also. A few weeks ago I restored a database back-up, but everything worked fine untill now.
Does anyone has an idea? I updated to the latest version and cleared the cache, maybe it'll help but I would like to know the reason behind these errors.
