psycopg2.errors.OutOfMemory: out of memory

[akki401]

Hi I started docker for europe planet file (europe-latest.osm.pbf) which gives the psycopg2.errors.OutOfMemory: out of memory error.
After all finishing the RANK 30, the docker started again from start and start indexing.

EC2 config:
i4i.2xlarge
vCPU = 8
Memory (GiB) = 64
Instance Storage (GB) = 1 x 1,875 AWS Nitro SSD
Network Bandwidth (Gbps) = Up to 12
EBS Bandwidth (Gbps) = Up to 10

Docker command:
cmd = " ".join(
[
"docker",
"run",
"--restart=always",
"--log-driver json-file",
"--log-opt max-size=10m",
"--log-opt max-file=3",

]
)

I felt the system configuration is good enough in terms of RAM and storage to run the europe continent nominatim
Let me know if anything need to change in the docker config command which I posted above
