What GregS said. The switching transient from 7 CFLs is causing them
to get confused. One incandescent in the string will "stabilize" the
voltage/current enough to allow them to light reliably.

(And it goes without saying that a dimmer should not be used on this
circuit, right?)

I tried 3 FEITS on kitchen dimmer. Had big problem, and I think
the biggest problem is FEIT brand. I have never before tried more than
one dimmable CFL on a dimmer. They must be dimmable of course.

Stay away from FEIT's.

Thanks for the idea. Unfortunately, it didn't help.

I'll try disassembling the light fixture and cleaning/upgrading the
wires.
