Network Stack errors on loading Startup-Config

Hello all, I have a stack that consist of a N3024, N3048 and a N3048P. This morning I issued a re-load command (like I have done countless times before). The stack came backup but my network was dead. After connecting in via the Console and ordering another reload I discovered that the switch only loaded the first 135 lines of my 2000+ lines config. I received the following: "The following lines in "startup-config" failed:  followed by the rest of the startup-config.

Active image version is: 6.3.2.7

Does anybody know why this might happen and better yet how to keep it from happening again?

thanks,

Bill
