Hi P’Yin
FYI .
From my observation , possibility from Network High utilization during 8.30-9.30 today as I capture to you .And also we got the alert about some packet lost during your batch file running sent data into Thailand . These are the first log from my side , if I have another log will let you know.
Please keep monitoring from your application as well . if found any abnormally .Please update .Thank you.
