Since last 4 days, we are facing strange issue on our Production server (AWS EC2 instance) specific to only one site which is SugarCRM. Issue is /home/site_folder/public_html/include/MassUpdate.php file is renamed automatically to /home/site_folder/public_html/include/MassUpdate.php.suspected This happens 2-3 times in a day with 3-4 hours of gap. This issue occurs only in case of specific site, even it doesn’t occur for staging
