Hi sorry I have a similar issue. I used to have a .rprofile with memory.limit increasing my actual RAM limitation but recently I tried to open a .rdata and it always tells me it s blocked at 16.2 gb which is my physical limitation but before with memoryu limit increased, it was able to get beyong. Not sure if the last update I did today messed that up. I tried to increase this R_max v size in renviron but it does not seem to work. any idea where it comes from?

it says: impossible to allocate a vector of size 16.2gb

thanks
