Error executing transfer

Hi,

We are currently running a few tests to see how well the Alfresco replication transfer service works in a poor network environment and we are experiencing transfer failures when introducing long packet delays into a low bandwidth network.

Under normal network conditions all transfers complete successfully but, when we introduce packet delivery delays into a lower bandwidth network (e.g. 500ms packet transmit delay, 500ms packet receive delay in a 256Kb/s pipe) we get the following transfer failed error when transferring data loads of over a certain size (roughly +1 MB data size in our tests so far):

Has anyone else tried the transfer service under poor network conditions before?

Thanks in advance for any help on this matter.

PM
