Prom-migrator mem killed

[kencafe]

Hi team, I have installed prom-migrator to migrate my Prometheus data to another storage.

I have installed and run it successfully but the process always was killed cause out of memory.
I have set time duration (2 minutes ), increment duration (1 minute), and file size (10MB) is too small but still an error.

prom-migrator -reader-url=http://localhost:9090/api/v1/read -writer-url=http://localhost:19291/api/v1/receive -progress-enabled=false -gc-on-push=true -start=1678886762 -end=1678888800 -max-read-duration=2m -max-read-size=10MB
