Cause of the Failures: The tests in DegreesWithExceptionITCase use the context execution environment without extending a test base. This context environment instantiates a local excution environment with a parallelism equal to the number of cores. Since on travis, build run in containers on big machines, the number of cores may be very high 32/64 - this causes the tests to run out of network buffers, with the default configuration.
IMPORTANT: Please make sure that all tests in the future either use one of the test base classes (that define a reasonable parallelism), or define the parallelism manually to be safe!
