Not likely, I’ve dedicated a full 16 gigs for wallet and it only used about 2gb when it crashed. Tried on both the 32 and 64bit version. The 64bit has access to the full 16gb’s of memory. Does the same thing from a fresh sync or from the provided blockchain. Bare in mind that the wallet has been tested on windows 7, 8, and 10. 64 bit.
I currently run 36 different wallets on the servers and the Nu wallet is the only one that is crashing on all windows versions with fresh sync and also from a downloaded blockchain.
