somethings about panic file

Dear sir:

 I write a code to generate layout(about more than 80000 layouts),but when I run it,sometimes the CIW window will show the information:

CellView(test1 layout) from lib(test) is saved in the panic file(/path/test/test1/layout/layout.cd-)

To recover do:

dbOpenPanicCellView("test" "test1" "layout")

And then,the icfb will closed by itself,and I have to rerun the code again.

I guess the reason is I generated too more layouts one time,isn't it?

If it is,how shoud I do

Thank you!
