I recall two or three occasions - a middle-of-the-night stop in Kansas City on the SFO-PIT redeye.
fwiw, the plane had plenty of fuel to get to SFO. But it needs to have fuel to get to SFO, then to some number of diversion airports that don't have weather issues, plus xx minutes of circling, etc. So they didn't have enough fuel for all of those safety measures.
SFO is about 100 miles past FAT, so it was close. But there's no "close enough" in the fuel calculations/regulations.
