yet again: uploads never finsh

[Frank Kruse]

My GT has been working fine for about a year now.

Since yesterday I can´t finish uploading a 1.7GB OMF I´m trying to send.

My setup hasn´t changed at all. I´ve tried to restart the upload without luck.

My server is at an external computer-center hooked up directly to a backbone and very fast (no port-filtering, no FWs, no proxies, no content filtering).

My local line is VDSL (25Mbit down/5Mbit up, ping 40ms).

The client starts off with an estimate of 10minutes for the 1.7GB then goes up to 30 minutes. After a while to 1.5 Minutes remaining then back to 1 hour. But the progress bar goes anywhere from almost done to almost not visible to stall (candy-bar). Normally this upload would take 15 minutes over my line but now the client didn´t even upload the file over night.

FTP at the same time is reliable and very fast.

Since it has worked for almost a year non-stop I have no idea what I could change to get it back to work.

Has someone seen this? Is the central site down again like a few months ago?

My other clients complain about the same thing. They are all over the place so it can´t be my uplink.

Weird thing is that sometimes the speedbar doesn´t show ANY "LED" at all (not even red) but the bar keeps showing.

Thanks,

Frank.

UPDATE: Just tried a 10MB-File. Same thing. I restarted the server. After that all seemed normal. Realistic remain times but then after 2 minutes the problem came back. (1minute remaining for something that should take 15minutes but then never finishes).

Frank - you may want to contact Aspera directly. They're here relatively often, but you'll get a faster response using their support system.

Thanks for chiming in.
I´m aware of that but I haven´t got a $upport-plan so I thought I´d check the "public-domain" support of other users first. Last time I´ve had a problem like this was when the digi central site was down.

Update:

After testing I´ve found that downloading from the server is fine only uploading shows the described weirdness.

I´ve tested this from various locations (even different cities via clients).

ISP says on their side nothing has changed and is fully functional.

Update:

ISP has confirmed that there is no content-filtering, no bandwidth limiting and all required ports are open.

I´m checking for a hardware faliure but I have no idea how that would lead to problems with uploads only.

There's plenty of drive space? Did you do a complete hard reboot? Check and reseat (or replace) ethernet cables?

It's definitely a strange problem. What happens if you uncheck 'Optimize for Internet Delivery' in the upload options?

It turned out that the logs of the server report that the en0-port constantly goes up and down.

I´m now checking what the cause is. Could be either that the ethernet-port went belly up or the cable is faulty or the switch-port or a combination of that.

ISP says it´s highly unlikely the cable/switch-port but I have asked them to change cable and/or switch-port before I go there to pick up the unit if that doesn´t help.

It´s similar to this:

What do the lights on the back of the DD Server show (if you can get at them)?

At least it seems you're on the right track toward a fix...!

[Frank Kruse]

After bringing the server back home the issue boils down to the en0 interface constantly flaping on and off every 3-4 seconds wich explains the huge lost package rate (70-80%) and hangs I was seeing
I´ve changed cables switches etc. without success.

Chris Markle has been great finding this. I´ve found a couple of posts on linux forums mentioning the same thing but since I´m no linux expert (although this case might turn me into one shortly ) I have no idea if this is hardware related or not.

Kudos to Chris for the great help so far.

I just hope the box isn´t fried since I don´t have another 10000$ lying around.

But as we say here:

Hope is the last thing that dies.

Just to complete the thread:

Although the issue has not been solved a work-around has been found. The port flaping only happens when connected to a gigabit-switch so I´ve hooked up the server via a fast-ethernet-switch wich isn´t an issue since the machine is located in a remote site anyway.
All works fine again.
Why this started out of the blue is unknown. Could be the hardware, could be something else.

A big thank you to Chris from Aspera!

Frank.
