sorry, the host got destroyed.

you can see from the test box that it is killing other processes too:

# grep "Out of memory" messages

It just happens that Mongo is the largest consumer at the time but doesn't necessarily indicate any specific issue with Pulp, just that these tests are consuming more than the 20G of RAM available to the test VM.

Based on Comment 8, closing this out.
