This upload (4MB+) is regularly timing out at 15 minutes

Please remember us Brits with ghastly slow ADSL upload !

Regards,

David

What client version are you using? Both servers mentioned in your log (130.237.165.141 and 128.143.199.97) should be set to allow a 45-minute connection time. I wonder if this is a client-side issue? Do you have >15 minute uploads working to other servers?

Sorry for omitting the info -- forgot this was not on the v7 beta forum!
This is on Linux 64-bit version 6.34. I have seen at least one 45-minute timeout on 128.143.199.97, it looks as if even that is not long enough (if time is the real issue).
I don't think there is anything at my end that would cause a timeout, though suggestions for Linux things to check are welcome (i am a Linux novice).
I am permanently connected via ADSL and the PC and hub run 24/7.

Here's some more info about upload time.

The results file is >41MB (typo in original email). My average upload speed is 6kB/s. So the upload time will be around 7000 seconds -- almost 2 hours.

Timeouts are occurring at either 15 or 45 minutes, consistently. I am fairly sure this is the server timeout -- can it be extended? otherwise I shall have to exclude big units (by dumping them if necessary) since results of this size will never be uploaded within the permitted transfer time.

If your upload speeds are 6kB/s, I'd recommend using the client option for small work units (<5 MB) or normal work units (<10 MB) to make sure you get work units that aren't too big for your link to handle within the allotted time.

i.e. uniprocessor WU's

Switching from one SMP client to multiple copies of the CPU client is also a good way to go.
