i was away for 1yr and decided to start from scratch to reflect any software updates. After importing my old seed, hit Settings -> Rescan Coins. The wallet starts downloading and scanning. This is done in RAM.
To avoid the inevitable crash when RAM use is 100% there is a simple workaround:
o monitor RAM usage (i.e. free -h on Linux, 930Mi free in my case)
o reload https://incognito.org/ when you have stille 300MB left
o log into wallet
o Rescan resumes where it left off, RAM freed.
The progress display may be missing but network and RAM usage show that the sync is going on in the background.
When free RAM increases (purging) and stays roughly constant resync is done.
On Brave the JS engine is extremely stable. Even when no free mem, brave stops the unresponsive script, thereby freeing RAM. No crash. (takes time though)
Nice to be back.
