571492 - check that mv-moz2-linux-ix-slave02 is OK

Status: RESOLVED FIXED

(Release Engineering :: General, defect, P2)

Description

[Armen [:armenzg]]

I have pulled this slave out of the pool since it made 4 builds (Linux mozilla-central build) to fail with the same problem.
This started happening on Jun 11 01:27. The slave, nevertheless, was able to do l10n repackages.


This is the problem we got on the set_basedir step:
bash -c pwd
...
error in ShellCommand._startCommand
Traceback (most recent call last):

I have put this slave back into the production pool since it stopped having that problem. I will watch how it behaves before closing.

We've seen this on other slaves too.  Somehow the permissions of /dev/ptmx get set so that cltbld can't open a pty.
