Job stops responding even before it has started

Hi All,
Sometimes I see the jobs stop responding, like today: https://travis-ci.com/github/sudipm-mukherjee/linux-test/builds/191615602

This was yesterday - https://travis-ci.com/github/sudipm-mukherjee/linux-test/jobs/403001982

My build script has not yet started and its just trying to setup the environment and it stops responding. Any idea what I am doing wrong?
The same CI script runs in travis-ci.org without any problem.

Thanks in advance.


Regards
Sudip
