XUpload - upload stops, then jumps to 100%

[mtspecial]

I am having more and more clients call me about this. They are uploading a file (mixed platforms and browsers on client end), when the upload stops and/or jumps to 100% and says upload complete. Nothing was ever uploaded.

I am using 2.5 Pro on OS X box. I have been using it for a while and for the most part it works fine.

Don't understand...progress bar was growing for them or not? File actually was uploaded or no such file exist in your uploads folder? Or maybe it's just POST redirect not working after complete upload?
Also check out your logs.txt file for details.

Random errors are worst ones

What they are telling me is that either the upload bar grows to about 10% and then stops or that it starts growing and at about 6% it then jumps to 100% and says that upload complete.

But now file was uploaded. The log file says that the upload was started, but thats it. No upload complete.

I meant to say "But no file uploaded"

Are you using AJAX update mode for progress bar(ajax_mode option in config)?

Can you check Apache logs for same time as you saw anomaly in logs.txt?

[mtspecial]

I started out without ajax mode and have switched back and forth a few times. i am currently using ajax.

the apache logs show nothing out of the ordinary...

I will PM you the logs i found.

been 2 months and haven't heard from you. Still happening to clients. The progress is working, but then jumps to 100%. Progress says done, but file is not uploaded.

Does it say "Transfer complete!" after jumped 100%? It looks problem happens cause upload.cgi killing somehow - maybe too high CPU usage, maybe runtime limit exceeded. But when progress jump to 100% it means upload.cgi died - logs tell same thing - no end part in logs.
Check out your server limits for CGI scripts with your administrator. If upload.cgi forced to die then I think there should be some message in some log file.
