[Bug 60283] New: Apache 2.2.15 + File Streaming = Memory Leak
https://bz.apache.org/bugzilla/show_bug.cgi?id=60283
Bug ID: 60283
Summary: Apache 2.2.15 + File Streaming = Memory Leak
Product: Apache httpd-2
Version: 2.2.15
Hardware: Other
OS: other
Status: NEW
Severity: normal
Priority: P2
Component: Core
Assignee: bugs@httpd.apache.org
Reporter: etornam.banini@cerner.com
Hi,
When downloading a large file from using rails, Phusion Passenger 5.0.18 and
Apache 2.2.15 the thread size will continue to grow the longer the download
takes. We are using this code:
path = '/home/data/test.tar.gz'
pack_content_type = 'application/octet-stream'
send_file path, :type => pack_content_type, :x_sendfile=>true
A number of file sizes have been tested and have found the larger the file, the
larger the httpd thread grows.
ie: 50 GB file => 2 GB httpd thread size
80 GB file => 3.2 GB httpd thread size
The downloads are done on a Red Hat 6.6 node and the behaviour/size is
consistant for every download.

Sounds like a potential passenger bug. If all of the rails/passenger stuff is
not necessary for the memory growth, please show a basic configuration and
memory growth observations for a static file.

We have looked into it from the passenger side and have determined that
passenger is not the cause of the memory issue. We are using a simple rails app
to download a static file from one folder and write it elsewhere. We are using
a simple curl to initiate the download.
