I saw this yesterday while looking through some logs. 171.64.65.124 very slow on upload and download, sometimes the work units are simply "dumped". Below is an example I saw again this afternoon. I have not gone through all of the logs (8 machines, all nearly identical) to get a list of the WU, but this is the only IP address that I have seen the issue with.

And I seem to be seeing "special" characters in the logs, unicode? I don't remember seeing those before.

This indicates a missing reply from the server -- either it was never sent, or it got lost along the way. Sometimes it has been blocked by AV or port security software at the client PC.

I *think* these (at least the ones in your log snippet) are escape sequences, probably newlines, which come from the original error messages. It looks as though a file was prepared in Windows but used in a Linux based build (or possibly the other way round).

These machines are still running naked as they always have , same networking setup.

I see them on the console (linux) as "ESC" in reversed text (white background). When I scp the logfile to my laptop (linux) and open it with Kate (K Advanced Text Editor) they show up as special characters. That part may not be important. The server and WU dumping issue still concerns me.

OK, the special characters are apparently for COLOR! When I cat the log either on the console or via ssh on my laptop, it is all monochrome. When I grep on the console, it is all monochrome. When I grep via ssh on my laptop, :ERROR is all red, and and :WARNING is all yellow. There is a difference in the shell setup between the laptop and the rack machines.
That makes me feel a bit stupid if it has been there all this time and I just noticed it . That's one mystery solved, anyway.

It's on its 5th attempt right now. Collection server says 0.0.0.0 , and work server is 171.64.65.124. My internet connection is just fine, and I haven't changed anything with my firewall. If it manages to send I'll delete this thread.
It looks like the WS may be having some problems, the Net Load has been running on the high side for the last couple hours. I have contacted the person responsible for that server.
Edit: I have received a response back that this is being looked into.

I noticed the same problems here last night and they continue this morning. For example (from my log), "... WARNING:WU02:FS01:Server did not like results, dumping ..." At least one other member of my team also reported issues with this server overnight.
It would be better to turn off assignments for projects hosted on this server until the issue is solved so that we don't waste CPU time because of dumped WUs and work on other available projects ...
