I am being plagued by OSPF adjacency drops in my network and there seems to be no reason why these occur, other than the dead timer expiring. The timers have been tweaked and I include my configuration + the syslog message that appears when I loss the adjacency. There is no extra load on the interfaces that could cause congestion. Any help well rated !!

The stange thing here is that the interface does not flap, the network is in fact stable. The only syslog I get relates to the dead timer expiring. This output is from a Cisco 3825 the other end is a 6506E with SUP720.
