As the testing code uses account db which requires lots of threads and access lots of files. We have to increase the vm.max_map_count and vm.nr_open. We will get 'out of memory exception' without this configuration change.
# in file /etc/sysctl.conf set / only to be done once per machine
vm.max_map_count=1000000
fs.nr_open = 1000000
To reload config :
sudo sysctl -p
export RPC_HTTP_URL="http://fcs-ams1._peer.internal:18899"
