Description
MySQL temp files can have a problem if users run antivirus software. There is a well-documented MySQL conflict with the "On Access Scan" feature of McAfee.
Symptom
The symptom is the following message in the virus scanner log:
Can't create/write to file 'C:\DOCUME~1\spg\LOCALS~1\Temp\#sql_d30_0.MYD' (Errcode: 17)
The message may be present in the commander.log file as a metadata message only:
