[galaxy-dev] Memory limit for a Travis CI build

Hi all, I submitted a PR to Galaxy Tools IUC (https://github.com/galaxyproject/tools-iuc/pull/2506). The Travis CI build exited with an error code 35072. The error may be caused by running out of memory. https://travis-ci.org/galaxyproject/tools-iuc/jobs/564531462 In fact, my program does not use too much memory on the test case (< 1GB). May I ask what is the memory limit to pass a Travis CI build? How could I request more memory if it is too small? Thank you. Best regards, Jin
