cisco 2924XL port down and up

[tian-lu]

In the last a few days, our cisco2924XL switch reported a couple of times that one of the ports was

down and up by itself with no reasons. The interval between down and up was one or two seconds. This port connects the file server and about twenty workstations. Could it be traffic overloading? But

it happened once in 3am. Could it be bad cable?

Any hints?

If you look at the interface stats for the port, are there any errors?

Also, are the speed and duplex manually configured on both the switch and server, and do they match? ie: 100/full, 10/half, etc.
