Thanks @felixcheung
So I had a look into the log file, below is some extract:

If you look at the timestamp, it took more than 7 secondes to create a few

was busy because not enough system resources. I guess the Travis CI server was
quite busy when we launched the test.
There is really nothing to do other than retry
