We run Serv-U 9 on a Windows 2008 R2 server.
We have used the Serv-U file logs to validate that we have received the expected files from a customer. However we can now see that not all files are logged. Some are just missing from the log even though they have been uploaded. It seems to happen when a lot of files are being uploaded at the same time, so I suspect it's due to the logfile being locked.
I have attached a bit of the log where you can see a file 01637 and 01639 being uploaded, but 01638 is also uploaded but never written to the log.
What can be done to get a valid log that we can trust?
