Hey all. I’m following the latest alpha guide, running ./qa/pull-tester/rpc-tests.sh and it fails the following test. I thought this might be helpful.

Hi, I have the same result, after freshly installed everything.

These errors are typically caused by a lack of memory in the system you’re testing with. The zcpourdoublespend test uses a very large amount of memory.

Okay, thanks for the reply. I’ll try on machine with more ram.
