And it constantly crashed with fatal error after the 323 wallet in the stage "load wallet.." (although all of them are first verified ok)
At this point the memory usage is about ~750 MB
I have enough available memory.

EXCEPTION: St13runtime_error
CDB: Error 12, can't open database wallet-333.dat
D:\Bitcoin\bitcoin-qt.exe in Runaway exception

Runaway exception might be caused because the wallet you try to open (wallet-333.dat) is not a HD wallet?
Are you able to open this wallet.dat individually? If not, you may try to start core with this command: -usehd=0

Does the same issue also appear when replacing this wallet file with another (working) one?
Or does it always crash after 323 loaded wallets?
