Hello,
We have a struts based application running on a Tomcat 6 server sitting
behind an Apache HTTPD Server.
I'm experiencing problems uploading big files on it: after around 30
minutes (nearly exactly 30 minutes!) the upload stops.
I've tried to solve them with several combinations but until now I
didn't find any solution.
In the "standard" configuration we have Apache HTTPD with mod_ssl
connected through *mod_proxy_ajp* to the *AJP Connector* of Tomcat.
Apache httpd-ssl.conf:
<IfModule mod_proxy_ajp.c>
ProxyRequests Off
ProxyTimeout 3600
ProxyPass /error !
<Location / >
ProxyPass ajp://172.31.252.17:8009/
ProxyPassReverse ajp://172.31.252.17:8009/
</Location>
</IfModule>
Tomcat server.xml file:
<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />
With this configuration I get a *FileUploadBase$IOFileUploadException*
("*Processing of multipart/form-data request failed. null*") with
following stacktrace:
----------------------------
org.apache.commons.fileupload.FileUploadBase$IOFileUploadException:
Processing of multipart/form-data request failed. null

On the Apache site (error_log) I don't have any message.
If - instead of mod_ajp_proxy - I use *mod_http_proxy* connected to the
*HTTP 1.1 connector*
<IfModule mod_proxy_http.c>
ProxyRequests Off
ProxyTimeout 3600
ProxyPass /error !
<Location / >
ProxyPass http://172.31.252.17:8080/
ProxyPassReverse http://172.31.252.17:8080/
</Location>
</IfModule>
<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" />
Than on the Tomcat site I also have a
FileUploadBase$IOFileUploadException but with a different message
"*Processing of multipart/form-data request failed. Stream ended
unexpectedly*":

----------------------------
and this time on the Apache error_log file following message appears:
[Wed May 20 11:34:45 2009] [error] proxy: pass request body failed to
172.31.252.17:8080 (172.31.252.17) from 172.31.252.1 ()
As I told you I tried several solution:
* using the last SVN version of *commons-fileupload* library (1.3
snapshot instead of 1.2.1)
* forcing in tomcat server.xml the parameter *disableUploadTimeout*=true
* In Apache setting the *Timeout* to 3600 seconds (1 hour)
* In the proxy configuration setting following properties:
*SetEnv force-proxy-request-1.0 1
SetEnv proxy-nokeepalive 1*
* Trying not to use HTTPS but connecting directly Apache on HTTP to
Tomcat
However nothing seems to help: after 30 minutes the upload breaks down.
To be honest I really don't know what to do.
Our application has an upload progress indicator, which is updated every
X seconds through AJAX calls: for this reason it's this not a problem of
session-timeout, which is kept alive through this calls.
Our Server is running Solaris 10, but I've also tried on a Linux (Suse)
with exactly the same result.
What could be the problem? Do you have any suggestion?
Please, tell me if you need some more information.
Thanks a lot for your help.
Best regards,
Patrick
