Description

We don't what is causing this but we should investigate it before it becomes more problematic (as of now it is taking CPU time).

It would be easier to know why if bug 1243020 was fixed.

More noticeable if we also include e10s jobs:

I know this was caused by my push [1] where I changed from 12 chunks to 8 and started trickling bug 1238435.

Armen just pointed us to a more recent failure,
  https://tools.taskcluster.net/task-inspector/#fIAKGG5qRWiQMgcSt7LXAQ/0
which still has (well, did a second ago) a live log.  It ends rather precipitously and unhelpfully:

The "live log" is fetched from the actual EC2 instance doing the work.  So we do have a datapoint here, in that the instance was still alive 12 minutes after the task was resolved claim-expired.  And we also have the instance ID and can look up some logging output from docker-worker itself via papertrail.

I see a reclaim of this task:

 Feb 05 07:53:20 docker-worker.aws-provisioner.us-west-1b.ami-c7f285a7.m1-medium.i-1ec2d9ac docker-worker: {"type":"reclaiming task","source":"top","provisionerId":"aws-provisioner-v1","workerId":"i-1ec2d9ac","workerGroup":"us-west-1b","workerType":"desktop-test","workerNodeType":"m1.medium","primaryTaskId":"fIAKGG5qRWiQMgcSt7LXAQ","primaryRunId":0,"taskId":"fIAKGG5qRWiQMgcSt7LXAQ","runId":0,"takenUntil":"2016-02-05T15:57:57.288Z"}

but no further reclaims after that time.  The queue resolved the task with claim-expired at 8:44.  Which doesn't seem to match up with the timestamps in the mozharness logging.

There's some state inconsistency in this docker-worker, somehow.

Ah, the mozharness timestamps are UTC (!?), so 16:26 utc (mozharness) == 8:26 pacific (papertrail).  So basically the tests up and quit at 8:26 in such a way that docker-worker forgot about them.

Feb 05 09:16:22 docker-worker.aws-provisioner.us-west-1c.ami-c7f285a7.m1-medium.i-a83ced6b kernel: [11945.137480] init: docker-worker main process ended, respawning 

In other words, an ENOMEM from docker-worker at about the time of the last log entry from the subprocess.  ENOMEM from fork tends to indicate kernel limits, rather than actual RAM/swap limits.  I wonder if the test is forkbombing?  Perhaps e10s isn't cleaning up zombies?

That instance is dead now, but if I see this intermittent again I'll try to connect to the host and see what's up.

Worth noting that the process docker-worker is spawning is `df -k` via the `diskspace` package.

so, that does seem like a lot of copies of runtests.py

In the host system, top shows

which is an awful lot for a host with 3.75GB of RAM, although vmstat doesn't show it swapping.  Just to check, Armen, these aren't the tests that we run on an m3.xlarge in Buildbot, are they?

In fact, I see things changing - RAM allocated and deallocated, CPU usage of processes changing, ..this is not totally wedged.  And now,

6214 ubuntu    20   0 3098180 2.347g   1664 S  0.7 64.1   0:58.68 python

so that Python process (one of the runtest.py's) is now using 2.347GB on its own.  I strongly suspect that something is deeply wrong with the test-runner in this case.

Looking at lsof, it's writing a great deal of information to /home/worker/workspace/build/blobber_upload_dir/wpt_raw.log

In /home/worker/workspace/logs/log_info.log I see logging far beyond that available from the livelog daemon, too.  And then the docker-worker process exited and killed the docker container (same logs as before, running 'df').

I suppose the thing to dig into is, why is the test runner using that much space?  Is it buffering output from some other process in memory?
Flags: needinfo?(armenzg)
My guess is that the logs are getting buffered unnecessarily. At least they are pretty large for this set of tests (some of the tests are generating multiple tens of thousands of results), and debug firefox produces a lot of junk output.

We can try a bigger instance and see if we behave better?

We spent a lot of time running these tests on this specific instance type, so that's probably not a good direction to pursue.  I wonder if there's some particular junk message that's being spewed repeatedly.

It looks like https://tools.taskcluster.net/task-inspector/#b2ZQqE7LTr6kMKY4mC58eg/0 is starting to hang the same way, so let me take a look there.

So, there are MANY more lines of output in log_info.log than in the livelog right now:

followed by about 140,000 lines of additional logging, and still going. It looks like the "normal" level of logging repetitiveness: lots of TEST-PASS, DOMWINDOW, etc.

James, what could we do to try to debug what runtests.py is up to?

This looks good but I think you would want "retries: 0" unless you want it to retry once.

garndt: I will land it with retry 0.

dustin: running on a larger instance clears this issue.

Adding NI for jgraham based on comment 16.

Well, I'm happy to see tests moved to desktop-test-xlarge, but perhaps not in this case.

One thing to note: Buildbot and docker-worker may be doing different things with tty's -- it's possible that runtests.py is talking to a pty on Buildbot and not on docker-worker, or vice versa.  If that might make a difference.

Bug 1246176 - TaskCluster web platform tests should not retry for infrastructures issues until bug 1246176 is fixed. DONTBUILD. r=garndt
So, in terms of the amount of output generated, that seems entirely reasonable. This chunk happens to contain some tests with many many subtests, so getting hundreds of thousands of lines of output is not unexpected. A recent W3-e10s on buildbot produced ~140,000 lines of json data which expanded to 210,000 lines when formatted in the TBPL style. Those files are 54 and 29Mb respectively, so not huge, but not tiny either.

In theory this data should not be kept in memory for the duration of the run; at least I don't think the mozharness layer, or test harness layer, do this, although I have not specifically checked (by more than code inspection). Presumably the live log view *does* do this.

To debug this further I guess using a tool like Heapy [1] or memory_profiler [2] will help.

The easier way for now would be to jump to the next bigger instance (I don't think we really need xlarge) only for web platforms tests.

We could leave this bug until we have time to look into it with more time.

fwiw, the live-log daemon is not caching in memory (and certainly not in runtests.py's address space, which is the one that seems to be growing to multiple GB's).

I see that wptrunner uses a bunch of threads, which is probably what we are seeing with the multiple instances in `ps` output.

Armen, let's put this on the m3.xlarge workerType for the time being.  I'll see if I can run this locally under memory_profiler.  Even if these tests work on an m3.xlarge, it's wasteful to be burning a 1.5G of RAM and will end up costing us a lot of money by preventing running tests in parallel on the same instances.
