Database Servers dropping connections, losing packets

The database servers, tahoma & baker, and the frontend forms servers snidley, dudley, and fenwick, began dropping persistent client Oracle and telnet connections. ICMP packets were also lost.

Speed and duplex settings on the switch ports to which these servers were connected were checked and found to be correct (100 Mbps, full duplex).

The problem cleared up after about 1 hour. Will check further.
