"Error: -maxmempool must be at least 9 MB" ⇒ did you limit the mempool or do you think that this was an RPC failure?

I think is a RPC failure, all the other tests are working. Where can I see this maxmempool parameter?

I don't know why, but running command solved the problem:

make distclean

And then running all again

I am running this command (using a 4GB temp HD mounted):

```
# test/functional/test_runner.py --cachedir=/mnt/tmp/cache --tmpdir=/mnt/tmp

```

And for all tests I get this errors:

```

```

Then I got this first file to test:

And only for it I got this error:

What else can I try to make all tests work? Thanks

Sometimes when you have previously built from source and then pull updates to the repository, it doesn’t correctly detect all the parts that need to be rebuilt. In that case, it can help to fully reset the build and start over. It seems that this was the case here and that’s why `make distclean` resolved your issue.
