>How about turning the problem around? Change the script in the page to detect the condition and just ignore it... until once it works and the user is back where he was. I mean the script which refreshes the toolbar and sidebars periodically.

When it happens, IOPS do not run across the entire network. We cannot access any disk. This means a hit in progress cannot be completed and the number of anomalies generated by such an event is random. I tried to put as much workarounds as possible. This has contributed to lower the visual effect. However, there is just so much I can do when a network is not working.
