Out of memory after some time run connect explorer to testnet

I got problem when run explorer service connect to Testnet follow introduction:

  • After some time I run explorer service, my computer out of memory and kill my process(I think it full queue).

So, Someone can help me:

  • how to optimize queue or limit RAM process
  • or tell me hardware required to run explorer(my computer RAM is 8G)

Increase your swap space to allow for this activity until the official test-net launches, will use way less memory then.
