 Posted: Fri 20 Jul '12 22:27 Post subject: Apache 2.4.2 Downloads are broken on huge files |
 |
|
Hell0,
i use normally the XAMPP for the Apache and all other stuff, but due to a problem I tried also the Apache from this website.
My problem:
If I download a file from my Webserver (even local) I don't get the file complettly downloaded.
Files I tested:
1 file with 376MB
1 file with 1,2GB
with the xampp apache the download stops between 210 and 280 MB.
with the apachelounge apache the dowload stops by 60MB.
Tested on IE9 and FireFox 13/14. The Browser tells me that the download is complete ....
Also other Persons tested it and got the same result.
So the problem seems to be the webserver. if i use the (old) apache 2.2.21 - the download is complete.
System:
Windows 2003 Standard with all updates
Microsoft Firewall
Can anyone else confirm this problem on his/her webserver or know a solution?
Best regards
Kagome

Anything in the Apache logs ?
What file extension(s) ?
Directly download or via a script (cgi, php) ?

There is nothing in the Apachelogs 
The access.log tells me that the transfere is ok (200)
File extension(s) are .rar and .exe
The download was directly - no script or anything else.
I tested it with a "plain" installation.
I downloaded simple the files from here (with SSL), stopped the xampp Apache, checked the Paths in the apachelounge apache and simple started the apachelounge apache.
I also tested the Apache 2.2.22 from here and with that version it works correctly. |

So nothing in the error.log.
And without SSL ?
Be aware with the SSL issue in 2.4. |

maybe the SSL was not correct explained.
I tried from this page here:
httpd-2.4.2-win32.zip
and now:
httpd-2.4.2-win32-ssl_0.9.8.zip
I started the Apache, tried to download (normal http) and stopped the apache.
access.log

The bytes are correct

Strange, looks the client (browser) side, Apache says all is OK. Not seen other reports.
What do you get downloaded in you download folder, nothing or partly ?
Using Compression/Deflate ? |

well, i tested on my location with different pcs and different browsers (Firefox 13/14 and IE9).
I asked also some friends to test the download.
A friend with a small internetconnection get only a few MB.
The Clients think that the download is complete. I have in my Download Folder a normal File - only the size is incorrect and the RAR-Archive tell me that it is corrupt.
Compression/Deflate - no idea - what is in the default settings?
I only changed in the httpd.conf the paths - nothing more.
I tested it now on my local PC (Win7 64bit) - there is everything ok.
Seems to be a problem with Windows Server 2003 o_O
I disabled also the Windows Firewall - no differnece.
I installed IPv6 Protocoll - no difference.
I really wonder why the Apache 2.2.22 is working correct. |

There are networking changes in 2.4 over 2.2, do not ask me the details 
Some limit setting somewhere in Win2003 ?
See Child: Starting 64 worker threads
You can try to up the setting in conf/extra/httpd-mpm.conf, who knows:
ThreadsPerChild 250
MaxConnectionsPerChild 0
Be sure you uncommented in httpd.conf:
# Server-pool management (MPM specific)
Include conf/extra/httpd-mpm.conf |

Networking changes are a good hint.
I added in the past due to slow transfere the following in the registry:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\AFD\Parameters]
"DefaultReceiveWindow"=dword:4e200000
"DefaultSendWindow"=dword:4e200000
If I remove that and reboot the server and try again the downloaded files are complete - but the speed is slow again (900KB/s - 1,2MB/s) instead of the normal speed (11MB/s - 12,5MB/s)
i will now play a little bit with the values and after that play with the Server-pool management.
edit:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\AFD\Parameters]
"DefaultReceiveWindow"=dword:00c35000
"DefaultSendWindow"=dword:00c35000
works correctly for me.
nearly Fullspeed and complete downloads.
I will make a small donation for the help.
I will now try to fix the following error if i stress-test the server >_<
| Code: | | [Sat Jul 21 16:29:14.139183 2012] [mpm_winnt:warn] [pid 724:tid 292] (OS 64)Der angegebene Netzwerkname ist nicht mehr verfügbar. : AH00341: winnt_accept: Asynchronous AcceptEx failed. |
seems to be the same problem as here:
http://www.apachefriends.org/f/viewtopic.php?p=90706
BUT if I add / uncomment Win32DisableAcceptEx - the Server doesen't start again and cry about a syntax error.[/code] |
