Issues with cloning repositores with too many branches over HTTP

Question

Hi,

I have problems cloning repositories over HTTP. The problem only occurs for repositories with over 12 branches, or with a total of 18 branches and tags.

Running the following command:
git clone http://USERNAME:PASSWORD@bitbucket.company.org/scm/key/repo.git

The cloning works perfectly fine when there is 11 branches, or a total of 17 branches and tags. When it is above that number the cloning fails with the following error:

error: RPC failed; HTTP 500 curl 22 The requested URL returned error: 500 
fatal: The remote end hung up unexpectedly

I have checked the atlassian-bitbucket.log and it does show an error related to the cloning of the repository:

The following was written to stderr:
fatal: the remote end hung up unexpectedly
com.atlassian.utils.process.ProcessException: Non-zero exit code: 1
at com.atlassian.bitbucket.scm.SummarizingProcessHandler.complete(SummarizingProcessHandler.java:47)
...

Bitbucket is running with loglevel DEBUG, and I couldn't find any more information in the logs.

Versions on server:

Bitbucket 5.14.0 
Git 2.19.0

Versions locally:

Git 2.17.1

I have tried to set the postBuffer:
git config --global http.postBuffer 524288000

I have tried to clone with Username and Password as input, and it still fails on more than 12 branches:
git clone http://bitbucket.company.org/scm/key/repo.git

It DOES work if I use SSH, but this is not an option for my use case. Since we have one release branch per release, and the number of tags do grow over time I would expect this to be a problem for other people as well. Does anyone have any idea on why this can happen?

Hi,

Thanks for the quick reply!

We do not have a proxy nor do we have a load balancer in front of our Bitbucket Server.

However I do see that Bitbucket fails when git http-backend is called. That is the last entry for this repo, if that is any help.

Thanks!

Hi,

Do you have a reverse proxy or load balancer in front of your Bitbucket Server instance? If you look at the logs, do you find any log entries for "StreamGuardFilter" saying something to the effect of :"the remote client has aborted the connection" for those failed clones?

In that case it would mean your reverse proxy or load balancer would be a fault and you should check on that side.
