I’m unable to start PhantomJS inside a Docker container inside CircleCI. I’m not sure what’s different about CircleCI, but these tests work fine on my local machine. On CircleCI, this is the output from running my tests: ```auto 13 07 2017 00:56:19.092:INFO [karma]: Karma v1.5.0 server started at http://0.0.0.0:9876/ 13 07 2017 00:56:19.094:INFO [launcher]: Launching browser PhantomJS with unlimited concurrency 13 07 2017 00:56:19.148:INFO [launcher]: Starting browser PhantomJS 13 07 2017 00:57:19.158:WARN [launcher]: PhantomJS have not captured in 60000 ms, killing. 13 07 2017 00:57:21.161:WARN [launcher]: PhantomJS was not killed in 2000 ms, sending SIGKILL. 13 07 2017 00:57:23.164:WARN [launcher]: PhantomJS was not killed by SIGKILL in 2000 ms, continuing. ``` ---

Sorry for the slow reply. I’ve been on vacation the last few days. This is for the `edison-ui` container (private). ---
