Hi Rsync Support, 

Recently we encountered issue on our prod environment because the rsync seems hanging, it took time building the list.Previously the rsync process was working before 10:24am not until 10:25am.  See sample log below. 
We have one source server and the data files will be rsync to 2 webservers. Please advise what could be the cause of the issue. 
Please let me know if you need more information.
