Hi Andy and Michael,
We need to enable CTS tests for few of the builds as they are a requirement for few projects. Is there anyone looking at the issue from the lava-dispatcher end since load could be an issue once we enable back CTS.

Hi, Andy & Michael
About the problem that the telnet process consumes CPU(bug1034218https://bugs.launchpad.net/linaro-android/+bug/1034218 ), For now I tried two ways to verify it:
- Run the CTS test via submitting a lava-job In this way, the process that consumes CPU is telnet
- Run the CTS test via command line "lava-android-test run cts" In this way, there is no process that consumes CPU to 100%, In the meanwhile, I also opened the telnet session.
So I guess the problem is the way we calling the telnet command in lava-dispatcher. From my investigation, it's the select syscall in telnet that consumes CPU, So I doubt if there is some place in lava-dispatcher that reads the ouput of telnet in a loop without sleep in the loop. but I did not find such place in lava-dispatcher.
How do you think about it?
Finally, I feel that this problem is of lava-dispatcher, not the problem of lava-android-test or CTS, so can we change it to be a bug of lava-dispatcher?
