Crash on Mac OS X when performing lots of requests simultaneously #315

pierresouchay · 2018-03-13T08:19:25Z

Hello,

In project https://github.com/criteo/consul-templaterb we use em-http-request heavily. The program never crashes on Linux, but on Mac OS, it crashes frequently (around 75% of time when performing more than 2k requests in parallel).

The bug does not seems due to ulimit -n file descriptors and really seems related to the latency of the server being reached, it looks like a race condition.

The program then crashes with the following information:

I can provide you a full test case if required.

It happens on this version of Mac OS:

Darwin C02Q3L7GG8WP 17.4.0 Darwin Kernel Version 17.4.0: Sun Dec 17 09:19:54 PST 2017; root:xnu-4570.41.2~1/RELEASE_X86_64 x86_64

aka Hi-Sierra, but I have seen the same errors on several Mac OS machines and operating systems including El Capitan and Sierra.

It also crashes on several versions of Ruby (2.3.x, 2.4.x, 2.5.x)

How can I help in order to fix this bug?

sodabrew · 2018-04-18T23:44:48Z

Thanks for linking this back to the source eventmachine bugs. I never did make any headway on understanding those crashes, but I recently got a possible clue, and will follow up with you on eventmachine/eventmachine#604 to discuss!

@sodabrew Unfortunately, updating to 1.2.6 does not fix the issue for me :(

Yeah, this crash is different and I’m able to reproduce, but it’s intermittent and I haven’t narrowed it down yet.

@sodabrew Thank you, yes, this fixed this issue, but there is another one :(

But globally, I don't have the previous error anymore

@pierresouchay Are you seeing these errors even if you're building EM from the tip of the 1.2-stable branch?

pierresouchay · 2018-05-11T05:40:45Z

Using 1.2.6
The previous fix increased stability : it crashes only sometimes now (1/10th of time) instead of 9/10th of time with 1.2.5

The previous patch really improved a lot, but it has still some issues, probably something different

pierresouchay · 2018-05-11T07:02:37Z

@sodabrew Sorry, I read too fast.

Yes, with the stable branch I don't have the issue anymore !

I launched my program 10 times without a single crash, the branch 1.2-stable definitely works well for me, thank you !

I can't wait for a release :-)

sodabrew · 2018-05-11T07:33:32Z

Thanks for confirming!

pierresouchay · 2018-05-11T07:51:32Z

@sodabrew Thanks for fixing it :-)

sodabrew · 2018-05-12T13:07:28Z

EM 1.2.7 is now released.

pierresouchay · 2018-05-12T14:33:39Z
