Community eB web server framework version 6.3.1.236 and version 15.5.1.236

After checking out a file, editing & saving the changes, then checking a file back in, the process appears to be hung with the message  "Checking in your files, Please wait...."  (see screenshot attachment). To remedy, the check in process is canceled, then "Undo Check Out" is selected. Viewing the file shows that editing was successful. What might be causing the check in process to hang? Is there a Web User setting missing? Additionally, the file does not show when undoing the check out (Screen shot attachment)
