[Buildbot-devel] IndexError

[Jeremy Cornett]

Hi,



I occasionally get this error:



web.Server Traceback (most recent call last):

exceptions.IndexError: list index out of range

/usr/local/lib/python2.7/site-packages/Twisted-12.1.0-py2.7-linux-i686.egg/twisted/internet/defer.py:551 in _runCallbacks

551                        current.result = callback(current.result, *args, **kw)

552                    finally:

/usr/local/lib/python2.7/site-packages/buildbot-0.8.7_Venafi-py2.7.egg/buildbot/status/web/waterfall.py:437 in call_content

436            return self.content_with_db_data(results['changes'],

437                    brcounts, request, ctx)

438        d.addCallback(call_content)

109    return builder.Results[result]

exceptions.IndexError: list index out of range



I don't know how to debug this issue. I always have to delete the logs off of the master to get the waterfall page to display again. Any ideas how to figure out what's going wrong?



Thanks,

Jeremy
