A single bacterium, doubling every twelve hours, with no death, would generate a mass of bacteria larger than the mass of the Earth in just over two months (I have assumed a mass of one picogram for a typical bacterium; The number of doublings to reach the mass of the planet is about 133, so at twelve hours per doubling, that's sixty six and a half days).I'm guessing that if it was more than a month or three, the Earth's biosphere might have been in serious danger.
It's unclear how any of the other immortal life would cope with this situation.
Mayflies mass less than a gram, but they're very fecund, with a single female able to produce between 100 and 12,000 offspring (depending on species).
Members of the genus Palingenia are at the top end of this range, and also are amongst the largest individuals, easily massing a gram per adult insect; Without mortality, five generations of these mayflies would significantly outweigh the planet (leaving the poor bacteria homeless and hungry).
