Adding more memory to VMs for rgw_multisite scenarios could avoid this error
I have recently hit in the CI:
(It is worth it to set 1024Mb since there is only 2 nodes in those
scenarios.)
```

This will setup 2 cluster with rgw multisite enabled.
First cluster will act as the 'master', the 2nd will be the secondary
one.
