After that client downloaded next unit from the same server (collection server also same) and uploaded it without problems. After client complete restart it automatically uploaded that unit, so it somehow stuck there.
When I noticed this issue, second WU after that was in 90%. That part of log contain all informations about weird WU. You can see logfile from entire day here. Like in previous post, issued WU is from time 13:13:08 like WU00 FS00
Your log shows four occurrences of "state:SEND" which are paired with only three "Upload complete" messages and it's not like your connection failed because the WU that hung is not the last one.
Only possibility I can think of is that either the ACK response from the WS that the WU had been successfully uploaded was lost between the WS and your system, or that the client missed it once it reached your system. That has been seen before on some ISP's or when the system is connected by a wireless connection. If you see this happening often, then you may want to look into your network connection.
If the WU remained on your system, it will eventually be deleted when the timeout is reached. Or you can remove it manually.
One suggestion, please return the logging verbosity to the default of 3. Higher settings rarely provide any useful information, and do get in the way of troubleshooting a client problem.
