Description Daniela Plascencia 2016-12-05 16:49:28 UTC

When executing patchtest on guest, the suite starts testing mboxes located at $BASE/mboxes, but after testing around half of them, the guest stops the patchtest execution with the following message:

/patchtest/mboxes/4134.1.mbox

/patchtest/mboxes/4135.1.mbox
/patchtest/patchtest/scripts/test-mboxes: line 86: /patchtest/results/4135.1.mbox.log: Too many open files
INIT: Switching to runlevel: 0
INIT: Sending processes the TERM signal

Right after halting, $BASE/results contains empty.json and .log files for the mboxes that couldn't be tested.

Comment 1 Daniela Plascencia 2016-12-21 16:03:17 UTC

When manually executed in guest, the following exception is raised before the suite tests all the mboxes, causing it to stop.

----------------------------------------------------------------------
Ran 4 tests in 0.197s

OK
Traceback (most recent call last):
  File "/patchtest/patchtest/patchtest", line 154, in _runner
    result = runner.run(suite)
  File "/usr/lib/python2.7/unittest/runner.py", line 149, in run
    startTestRun()

This is not related to the reported issue. Please file a bug and make sure you provide enough info; also indicate if pt execution @ host has the same issue.

Comment 3 Daniela Plascencia 2016-12-21 23:00:16 UTC

The message no longer appears using the script [1] to create and launch the guest machine. Resolving this as NOTABUG.
