Xencenter timeout issue

[Preeti Nandal1709161465]

We are using Xencenter 7.6 and trying to import VM, which takes about three and half hours to import. While importing Xencenter losses connection to Xenservers and the import fails.Below are the logs which points towards session time out. Is there a way to increase the idle time for Xencenter.

The default timeout for process under XS 7.6 is 24 hours, hence some other form of network issue may have been responsible. Are you doing this over the primary network interface or another one? Does dom0 have enough resources (run "top" from the CLI  to see what the load is)?
