Version: RChain Node 0.9.4.git32658c26 (32658c26300cd7672101d4e459f2bf85eaf1e827)
Max heap: 8GB

When using wallets.txt file linked above with cca 16k entries, genesis block creation on bootstrap node takes 2 days until the node finally fails on out-of-memory error. During those 2 days all available CPU time on 2 CPUs was spent by the node code (actual computation, in user-space, time in system calls was negligible). The debug data link above contains all that was captured: logs, OOM heapdump, JVM info.
