I am using xampp on Windows 7 using php against a mysql database. For certain queries, specifically a SHOW statement as opposed to SELECT, mysql returns a temporary file with the results which are processed by php. Unfortunately, NOD32 is grabbing that file and preventing mysql from deleting it. This all happens in a matter of millseconds: execute query, process results, delete temp file. The issue occurs about 50% of the time - when there is no issue I assume NOD32 did its 'thing' before mysql went to delete the file or after mysql finishes. I have confirmed NOD32 is the issue because if I disable NOD32, the problem goes away. ESET support said, "Open ESET, hit F5 to access the advaced setup, go to real time file system protection, click on setup, click on extensions, uncheck scan all files and click ok." Hence, I have told NOD32 to ignore these temporary mysql files (they have a .MYD and .MYI extension) everywhere I could. All to no avail - it simply will not ignore them (I have rebooted to be sure). I sent ESET the settings export file but I have received no further response from ESET in a week now. Does anybody on this forum have a suggestion?
