Re: apachectl -k graceful abort downloads (Apache 2.4.7)

[Sven Baumgartner <sven.baumgartner@xxxxxxxxx>]

It is not served with a third party code. MPM worker works fine. Is this issue config related or an unexpected behavior?

Hi,

I'm discovering an issue when gracefully restarting apache (apachectl -k graceful) that running downloads are aborted. In various web-browsers it looks like the download has finished successful but after checking the size it is clear that it didn't. Many times the download continuous until approx. 62MB and stops than if the graceful restart was before 62MB after that value the download abort immediately. I tested with 100MB and 200MB files.

How could I prevent apache from aborting the running downloads?

This type of failure during graceful restart is unexpected unless you are using some third party code.

Is the file served by httpd itself, such as a file under htdocs, or is it served from some third-party module or CGI script?

Have you tried with the worker MPM instead of the event MPM?

Thanks a lot for your help!
Sven
