We're trying to run Linux 64 debug tests inside of docker containers. In the following push [1] we have the e10s crashtest crashing [2]. If you "inspect the task" [3] you will see the .dmp files generated [4] There is also a screenshot of a dialog saying "The application classic guest session has closed unexpectedly" [5] I don't know if the following line in the output is relevant: > [Parent 1002] WARNING: pipe error (57): Connection reset by peer: file /home/worker/workspace/build/src/ipc/chromium/src/chrome/common/ipc_channel_posix.cc, line 459 The test in question is this one: https://dxr.mozilla.org/mozilla-central/source/dom/canvas/crashtests/780392-1.html Any thoughts on what could be causing this crash?

It's the other process realizing the pipe it uses for IPC has been closed.
Attached file stack —
Here's a stack from that minidump.
I already gave Armen some tips to check yesterday. But I had another look at the log and found the following: > 21:40:12 INFO - 'download_minidump_stackwalk': False, This explains why it is happening. The reason for that is the following config file which you make use of: https://dxr.mozilla.org/mozilla-central/source/testing/mozharness/configs/remove_executables.py
I will move the lack of dumping to its own bug and leave this one for crash itself.

Here's annotated disassembly of the crash location, if it helps anyone.
Hello poiru, we're seeing some crashes when running e10s crashtests inside of docker containers (we're moving towards them). ted has a crash dump on comment 5; would you be able to look into this bug and let us know if we need to change anything in the docker image? Thanks!

I only moved that test from one directory to another (you can use `hg log --follow` to track across renames). The test was originally added in https://hg.mozilla.org/mozilla-central/rev/8a736f13c5f8 You might want to try the author/reviewer of that commit.

Thanks poiru. My bad. Hi nrc, bas, we're seeing some crashes when running e10s crashtests inside of docker containers (we're moving towards them). ted has a crash dump on comment 5; would you be able to look into this bug and let us know if we need to change anything in the docker image? Thanks!

Removing NI as by now too much has changed and we will need new data. If we still hit the issue we will reflag and hope for better 2 way communication.

nrc, bas: please let us know if you could have a look at this or if someone else could. This is going to start getting a lot of attention so please help us at least redirect if necessary. Thanks for your help! We want to run Linux64 debug test jobs under docker. We're getting closer to it, however, we now have to figure test issues. In this bug we would like to look at fixing a crash we're seeing in e10s crashtest [1]. Here are the steps to reproduce locally: # First time prep step sudo apt-get install v4l2loopback-dkms # Every time after your host is rebooted sudo modprobe v4l2loopback # This will create a device under /dev/video* NOTE: The value --device is specific to your host.

This is possibly related to the stuff Jeff is already trying to resolve (so far without a lot of success.)

This looks like it might be caused by an unaligned access in the sse2 code. I'll try to investigate further.
if you would like to push to try or get some help, just ask- I would rather this be more teamwork than dumping bugs over the fence!
ncameron said in an email that it's been too long since he's touched anything in this area. jrmuizel: let me know if there's anything I could try. Thanks for looking into it!

I will be disabling the test for now as it is the last issue we have for tests on docker.

jrmuizel and I spoke about this and we're going to try to determine what is the space left, memory and ulimit. We should also compare with the job on the releng host. For now, we will get results in less than an hour for TC: https://treeherder.mozilla.org/#/jobs?repo=try&revision=e065f476de1b

The crash has *just* dissapeared.

It seems that the new crash is intermittent. The older one was permanent. I will push again *without* disabling the perma issue. I've got a new instance of the new crash [1] This time 852293.html crashes on SIGABRT [2] It seems that we have both SIGBUS and SIGABRT crashes. The script does not give me the disk space and mem because I put the code in the wrong place, however, I have the space before the script run [4] The starting free memory is a little less (46.7% free vs 68.9% free) than the time that it run without a crash (comment 23). > total used free > Total: 3748 1996 1752 vs > total used free > Total: 3748 1167 2581 On the good run, we go from 2581 MB free to 1395 MB after execution (that is 1186 MB less). However, we don't know if at any given moment we peak higher than that. Should we get the output of ps aux? or something similar?

Yes, ps output would be good. I'm not sure exactly what those statistics are showing, since in [4] there are two different numbers listed for cache and buffers. The kernel tries to make memory useful, caching disk blocks and other potentially useful information, and I don't know the details of how it represents that here. At any rate, even if firefox-bin used all 3.75G of RAM, once that process exited, you wouldn't see anything in the output. So I'm not sure this is a good way to chase down this particular issue. In particular, running out of memory generally ends in SIGTERM/SIGKILL, not SIGBUS or SIGABRT. To verify, I cobbled together #include <stdlib.h> #include <stdio.h> #include <unistd.h> #include <sys/types.h> #include <sys/wait.h> void main() { int pid; int status; if ((pid = fork()) == 0) { while (1) { malloc(1024*1024); } } else { wait(&status); printf("exit status %d\n", status); printf("WIFSIGNALED %d\n", WIFSIGNALED(status)); printf("WEXITSTATUS %d\n", WEXITSTATUS(status)); printf("WTERMSIG %d\n", WTERMSIG(status)); } } and sure enough dustin@dustin-moz-devel ~/p/m-c $ ./tmp exit status 9 WIFSIGNALED 1 WEXITSTATUS 0 WTERMSIG 9 where 9 is SIGKILL. SIGBUS, as Jeff pointed out in comment 15, is more often associated with misuse of memory -- usually unaligned access (as an invalid address would end in SIGSEGV). That the failure was in sse2_blt in comment 15 certainly points to that, too! And alignment would generally be intermittent, probably with some binary fractional probability (1/2 of runs fail, 1/4 fail, 1/8 fail, etc.) Basically, I think Jeff is going in the right direction here. I wonder if a good debugging technique would be to add some assertion about alignment: diff --git a/gfx/cairo/libpixman/src/pixman-sse2.c b/gfx/cairo/libpixman/src/pixman-sse2.c --- a/gfx/cairo/libpixman/src/pixman-sse2.c +++ b/gfx/cairo/libpixman/src/pixman-sse2.c @@ -4724,16 +4724,18 @@ sse2_blt (pixman_implementation_t *imp, src_stride *= 4; dst_stride *= 4; } else { return FALSE; } + assert(dst_bytes & 0x7 == 0); + while (height--) { int w; uint8_t *s = src_bytes; uint8_t *d = dst_bytes; src_bytes += src_stride; dst_bytes += dst_stride; w = byte_width; and then see if that assertion fails. It's worth noting that the source uses unaligned operations, so I think only the destination needs to be checked. I'm not sure which NS_ macros are available here, but I'm sure Jeff knows :)
It seems that ulimit -a is what we really wanted. Releng host [1] Docker instance [2] For giggles, running docker on my local machine gives different values [3] Did you want ulimit -a to be run *after* the test jobs? or is it fine before it? The clear differences I see are pending signals, open files and max user processes > pending signals (-i) 29669 > open files (-n) 1024 > max user processes (-u) 29669 vs > pending signals (-i) 29509 > open files (-n) 524288 > max user processes (-u) 1048576 Is this information relevant?

It looks like this probably caused by the size of /dev/shm being too small. In docker it defaults to 64MB but we likely need more. See also: https://github.com/jvermillard/docker/commit/77faf17586cecacf79765d47983363962827cb45
