> What's your question? Heh, yah that might be important... Has anyone experienced this? Does it look like anything in the my.cnf could be altered to alleviate or assist me in diagnosing the problem? I do not get an indication of any problems in the log files or the bin-logs. How might I efficiently trouble shooting this, where might I begin? I can't figure out how to replicate it, it seems to be quite sporadic. What would corrupt query results, temporarily fixed with a mysqld restart?
