Cisco 3560G GBIC port problem

We have two Cisco 3560G switches and are running  cat-5 between them using the gbic ports (using the plug in adapters). At night the gbic's have been going down, acting like nothing is plugged into them. If i unplug the cables and plug them back in it comes up. It has never gone down during the day with high activity.

Any info or expertise on this would be greatly appreciated. There are no error or warning logs on the cisco's.

Thanks for all the info guys, I'll be trying a number of combination's this week and will let you know what i find. I've got a replacement gbic and have tried replacing 1 of the units over the weekend but it happened again. I'll try replacing the other gbic and if it happens again i'll try a different port. (I'd think if it was the port there would be something in the error log. on the Cisco unit)
