[Bug 48130] New: DAV operations on large filesets consume all the server memory

https://issues.apache.org/bugzilla/show_bug.cgi?id=48130

Summary: DAV operations on large filesets consume all the
server memory
Product: Apache httpd-2
Version: 2.2.14
Platform: Other
OS/Version: AIX
Status: NEW
Severity: normal
Priority: P2
Component: mod_dav
AssignedTo: bugs[at]httpd.apache.org
ReportedBy: ville[at]jussi.la


Compiled apache with --enable-dav with gcc version 4.2.0. AIX OS level is
5300-08-04-0844.

Enabled DAV for NetApp vFiler filesystem (=network mounted) including up to 57
directories each holding 3000 to 20000 files. Filesystem is holding
approximately 70 Gigabytes of data.

Apache2 installation and DavLockDB located on SAN-volume.

Listing directories via a browser (without DAV) does not make httpd to increase
memory allocation when browsing through directories. Everything works nicely.

Listing directories via Windows XP SP3 DAV-client makes httpd to allocate more
and more memory when opening directory after directory. Everythings seems to
work, but more and more memory is allocated and nothings seems to be freed. In
the end, all the AIX memory is allocated by the httpd and AIX starts to kill
processes.


DAV enabled with :
<Directory "/netapp/...">
Dav On
Options Indexes
Order Allow,Deny
Allow from all

AuthType Basic
AuthBasicProvider file
AuthUserFile /home/.../httpd/conf/passwords
AuthGroupFile /home/.../httpd/conf/groups
