Aws-cli: Uploading files to S3 from EC2 instances fails on some instance types

What version of the CLI are you using? This looks like https://github.com/aws/aws-cli/pull/594, which was fixed in 1.2.11

Actually, that issue was for downloads, this one is for uploads so it's likely a different issue. I'll need to look into this further. If you could provide a --debug log of this, it would help in troubleshooting.

Also approximately how many 10M files are you uploading at once?

I'm also having issues uploading to s3, but from my laptop (OSX mavericks). A 424KB file failed,
and a 344KB file worked. I'm uploading one file at a time, with the following versions:

awscli==1.2.13
boto==2.24.0
botocore==0.33.0

The error is the same as the original post:

upload failed: ./test to s3://<bucket>/deploys/test HTTPSConnectionPool(host='bnch.s3.amazonaws.com', port=443): Max retries exceeded with url: /deploys/test (Caused by <class 'socket.error'>: [Errno 32] Broken pipe)

I ran it with --debug, and here's the part that keeps on retrying:

We are using version 1.2.13. We have about 200 of these files to upload, but we are doing it in series. The problem always happens on the first one.

Here is the debug log of the failure that you asked for: https://gist.github.com/benbc/8861033.

Is there any update on this issue. I'm seeing Exactly the same issue trying to upload to a newly created bucket.

Yes I believe this should be fixed now in version 1.3.0. The root cause I believe is the same as https://github.com/aws/aws-cli/issues/544.

Can you please try with the latest CLI version. If you're still seeing the issue, please attach a --debug logs and I'll repoen the issue.

i'm still having this issue upload to s3, neither from my laptop ,nor from debian server .The file is about 100MB. I'm uploading one file at a time, with the following versions:

   aws-cli/1.3.1 Python/2.7.3 Linux/3.2.0-4-amd64
   aws-cli/1.3.1 Python/2.7.5 Darwin/13.0.0

I'm reopening this issue. After debugging this I can confirm what others have said. This problem exists when trying to upload a large file to a newly created bucket that's not in the classic region.

From what I can tell the CLI is properly retrying requests and following 307 redirects. The problem, however, is that the CLI sends the _entire_ request and then waits for a response. However, S3 will immediately send the 307 response before we've finished sending the body. Eventually it will just close the connection, and if we're still in the process of streaming the body, we will not see the response. Instead we get the ConnectionError as shown in the various debug logs above.

The normal way to address this would be to use the expect 100 continue header. However, the HTTP client we use (requests) does not support this. There might be a way to work around this, but I'll need to do some digging into the requests library to see the best way to fix this issue.

I'll update this issue when I know more.

Any news?

my tests show that even when the boto library is failing, the AWS CLI works fine. what is the AWS CLI doing differently?

I don't think that there's any ways to workaround with in the requests library. I think our best option (aside from writing our own HTTP client that supports expect 100 continue) is some specific workaround in the S3 code.

I've just hit this too. My file isn't large, just a few megabytes.

Getting this with a 323KB CSS file.

Working on a fix for this, will update when I have more info.

Getting same issue when uploading large file (3GB) into S3. Uploading small file is just fine.

I'm getting a similar issue intermittently (about 1 file in every 20, files are around 500MB) using the requests library directly as we're working through our specific storage API. This is uploading from an EC2 instance.

Just an update, still working on this. The most viable approach so far has been to subclass HTTPConnection and try to implement the expect 100-continue logic in our subclass. We'd then plumb this into urllib3's connectionpools, which will be picked up by requests (which is the http library we use).

So I believe I have a potential fix, but it needs more testing. Will update when I have more info.

@jamesls as soon as you have a public branch to test, I'll be using it :)

Hi there,

since its not explicitly said in the thread, you can still use the "aws" command to upload files to another region by specifying the --region param.

• This one FAILS
  aws s3 cp ./really_big_file s3://MY-BUCKET/
• This one WORKS
  aws --region eu-west-1 s3 cp ./really_big_file s3://MY-BUCKET/

@inedit00 Thanks! I had no idea that this was related to the problem.

The fix for this is here: https://github.com/boto/botocore/pull/303

But I'd like to do more testing on this. I also want to see what sending the expect 100-continue header does to perf.

We are getting this error also when copying a large file (~3GB) from local to S3 (Ireland). Using aws-cli/1.3.17 Python/2.6.6 Linux/2.6.32-71.29.1.el6.x86_64 and botocore 0.51.0.

Just a quick update, the fix for this was in boto/botocore#303, however we caught a regression that was only in python2.6 so we had to revert the PR.

I think it's still possible to fix this, but it will be slightly more invasive due to internal changes in httplib from python2.6 to >python2.6. I'll update this when I have more info.

I was able to fix the python2.6 issue in the previous PR to fix this issue. All of the tests are passing with this change, and I can confirm that this fixes the issue of not being able to upload large files to newly created non-standard S3 buckets. Please let me know if you're still seeing issues, and thanks for your patience while we resolved this issue.

Thanks for the fix @jamesls. Which awscli release is/will this fix be in?

This is available in the latest version of the CLI (v1.3.18).

Also, if anyone is needing to debug this in the future, you'll see debug logs related to the expect 100 continue header:

That looks like a different problem. The errno is different, in particular.

got the same issue.

Reaching the performance limit of AWS s3?

I'm experiencing the same issue. This thread is rather old. Is this issue still being investigated?

Ditto. +1
Filesize: 1G
aws-cli/1.15.12 Python/3.4.3 Linux/4.4.0-71-generic botocore/1.10.12

For my setup this was resolved by setting:
s3 =
max_concurrent_requests = 5
max_bandwidth = 210KB/s

in the .aws/config file for the profile I was using. See here: https://docs.aws.amazon.com/cli/latest/topic/s3-config.html#

I'm having the same issue as well, when I tried to upload a file to s3 bucket using boto3 python package.

It used to work fine until about 4 days ago, and since then having problems with uploading.

I am having the same issue with a newly created bucket in the eu-west-1 region.

Command used:
aws s3 sync . s3://<bucket_name> --profile test --region eu-west-1

$ aws --version
aws-cli/1.11.13 Python/3.5.2 Linux/4.13.0-45-generic botocore/1.4.70

Is this problem related to the network I'm connected to? The upload was failing when I had connected to a 4G dongle, whereas when I was connected to my wifi router, everything was fine.

But, the 4G dongle was giving me 10Mbps speed. So, not sure where the problem is

@uldall If you haven't already solved this, for me this was fixed by installing the latest version of the aws-cli - the latest version on apt-get is outdated and so you must install using pip. Here's the instructrions:
https://www.slashroot.in/how-to-install-and-configure-aws-cli-on-ubuntu-16-04

On ubuntu 18
Install python 3
sudo apt-get install python3-pip
pip3 install awscli --upgrade --user
aws s3 sync ./ s3://mybucket01
