I have a network with a 2950 C switch set up with 2 Vlans a Data VLAN and a management VLAN. There are 2 separate uplinks to the ASA, one for each VLAN. The problem is that servers that are on the Data VLAN periodically drop their connections to eachother you can't ping you can't from one to the other connect to them on ports that they service. At the same time you see errors in the logs on the ASA saying that Server A on Inside can't connect to Server B on Management. All the servers are on Inside not management and you can see the server drop out of the ARP table on the other servers or they show the ASA Mac in the ARP entry for the server that cannot be pinged.
