500 error when attempting to upload files >60K

Hi,

I have a problem whereby Apache logs a 500 error and IE gives a page
cannot be displayed notice when I attempt to upload files of size
greater than approximately 60KB. The upload in question uses the POST
command to allow users to store arbitrary documents on the server.

I know that the upload script works correctly since I am using Apache
purely for it's virtualhost functionality, and when entering the full
URL and port number (thus bypassing apache completely), this problem
does not occur. Nothing appears in the error_log, though the
following entry appears in the access_log:

10.160.132.115 - - [01/Mar/2004:09:53:34 +0000] "POST
/coe/secure/uploadLOB.do HTTP/1.1" 500 639

I have tried altering various httpd.conf settings as detailed in the
Apache documentation - LimitRequestBody, LimitRequestFields,
LimitRequestFieldSize, LimitRequestLine, LimitXMLRequestBody - and
although I am able to further reduce the size of files that can be
uploaded, I have been unable to increase it past 60K.

I have searched for answers both on the apache homepage and on google,
but have so far not been able to resolve this issue. Any pointers
would be greatly appreciated!

Thanks,

David.

Just to rule out some possibilities,

does the machine have enough memory? Try to decrease 'threadsperchild'
in httpd.conf and see if there is any improvement at all.

Is this a module specfic problem? Try to execute a script using a
different module other than the one your current script is using. This
way you can narrow down on the problem.

In case anyone is interested, I have now managed to solve this
problem. It was down to the fact that when proxying POST requests,
the weblogic proxy module firstly saves the uploaded file locally in a
temporary directory before forwarding it on. This directory
(/tmp/_wl_proxy) did not exist on my server, as soon as I created it,
everything worked perfectly.
