Ken,

It could indeed be related to Apache2.  I have the problem on both a 
remote RedHat system and a local FreeBSD system.  They both run 
Apache2.  However it only happens for me using mod_webkit2, not using 
WebKit.cgi.

This may be the same socket-related problem theorised by John Goodyear 
(see [Webware-discuss] Random AppServer Lockups? and [Webware-discuss] 
Unhappy with Adapters).

I can reproduce the upload corruption at will.  The corruption does not 
occur in the same place every time, but seems to be about 2k-4k in 
length.  The content of the corruption is a repetition of a portion of 
the file immediately preceding the corruption.  The part of the file 
that has been replaced by the corruption never appears.  The file 
continues uncorrupted after this, until the next corruption.

Can anyone suggest other things I should test?  I'm a loath to install 
Apache 1.3, but I will if someone who has a handle on mod_webkit2 
thinks it is worthwhile.
