Connected to network but no synching any more

[es.blofeld]

Hi

Having a problem with my wallet all the sudden (used to work fine over the past few weeks) using QT Client v 0.8.1 which doesn't synch anymore.

It reports a backlog of approx. 600 blocks (growing) and just sits there "synchronizing" but nothing appears to happen for the last 24h. The client reports 8 connections to the network.

Any suggestion / pointer most welcome !
