I found there was a post named "Create Artwork Error" posted last year, while there is some differences in my case.
My OS is windows7 32bits, Allegro PCB Design XL (Legacy), 16.6 S008(v16-6-112AD) [4/16/2013]
When I was trying to create gerber, this error happened.

It seems I used a Flash Symbol, 20_DIAMOND, but Allegro can't find in library. I wanted to know which pad was using this flash symbol, and I can draw one myself. So I wen to Tools->Padstack->Modify Design Padstack.., I went through all these pads one by one, but I didn't find it. Is there any other way to find it, or I should set some parameters before generating gerber?
Any input would help.
