Hi all,

Im running it on VirtualBox (conf: 6GB RAM and 3 cores). When I ran the command:

./qa/pull-tester/rpc-tests.sh

Execution failed to have little memory (bad\_alloc) at this point: “zcjoinsplitdoublespend.py”, so I incresed the memory of the VM above 7 GB and the test ended well.

1. Would it be correct to reduce memory back to 6 GB?  
Allocating more than 7 GB to the VM, my imac becomes too slow (it has 8 GB)

2. Failure to pass the test with 6GB means that config isnt correct (VM w/6GB and 3 cores)?

3. This test is similar to the compilation? Where a lot of memory is required to compile but not so much to mining.

thanks
