Sebenarnya, saya memutuskan untuk mencari kesalahan Anda di Google, dan setelah membaca utas ini:https://github.com/felixge/node-mysql/issues/832 Saya menyadari bahwa Anda tidak melepaskan koneksi setelah kueri pertama selesai, sehingga kumpulan tidak pernah mencoba mengeluarkan Anda yang baru. Anda benar bahwa koneksi yang basi mungkin menjadi masalahnya. inilah cara Anda memperbaikinya jika:
upload.on('begin', function (fileInfo, reqs, resp) {
var fileType = resp.req.fields.file_type;
var originalFileName = fileInfo.name;
var renamedFilename = file.fileRename(fileInfo,fileType);
/*renaming the file */
fileInfo.name = renamedFilename;
/*start: log the details in database;*/
var utcMoment = conf.moment.utc();
var UtcSCPDateTime = new Date( utcMoment.format() );
var activityData = {
activity_type : conf.LIST_UPLOAD_BEGIN,
username : test ,
message : 'test has started the upload process for the file',
activity_datetime : UtcSCPDateTime
};
reqs.params.activityData = activityData;
req.getConnection(function(err,connection) {
var dbData = req.params.activityData;
var activity_type = dbData.activity_type;
console.dir("[ Connection ID:- ] "+connection.threadId+' ] [ Activity type:- ] '+activity_type);
var insertQuery = connection.query("INSERT INTO tblListmanagerActivityLog SET ? ",dbData, function(err, result) {
if (err) {
console.log("Error inserting while performing insert for activity "+activity_type+" : %s ",err );
} else {
console.log('Insert successfull');
}
/// Here is the change:
connection.release();
});
});
/*end: log the details in database;*/
});
