Bug 59090

We are currently facing an Issue in Apache 2.4.18 Server running on Windows 2012 Server with a WebDav Application -> Module mod_dav_fs

The Client which access the WebDav gets randomly the following ERROR: org.apache.http.NoHttpResponseException: XXXX:80 failed to respond.

I was able to reproduce the issue with JMeter
-	40 Threads which call “GET Requests” on a specific file
-	Randomly some calls fail with the above mentioned error
-	Small files generate less errors than bigger files

Same testing on a UNIX environment (RedHat), results in no ERRORs. SO it looks like it is somehow related to Windows OS.

Configuration for WebDav:
DavLockDB H:/Apache2.4/conf/davlock/DavLock
Alias /webdav H:/DATA/WEBDAV_ATTACHMENTS

<Directory H:/DATA/WEBDAV_ATTACHMENTS>
Options +Indexes
AllowOverride None
ForceType application/binary
Order allow,deny
allow from all

Dav filesystem
DavDepthInfinity on

require user XXXXXX
AuthType basic

</Directory>
