Hung during simultaneous download of large file

[K C Lau <KCLau@xxxxxxxxxxxxx>]

Hi,

After upgrading from Enhydra 3.1.1 to Enhydra Server 6.5.1, we encountered 
this problem:

When more than one client is downloading a large file at the same time from 
our Enhydra application, only one can complete while the others will hang 
forever waiting for the request to complete. We first found this problem 
with Flash swf files of around 1 MB in size but confirmed that it also 
happens to other files such as large jpg files.

It is ok when downloading different files at the same time.

We tried downloading the same file using FileServlet and it was ok.

We also tried with Enhydra 3.1.1 and it was ok too.

Our platform is Windows 2000 Server running Jdk 1.4.2.

Has anybody had the same problem?

We noticed that there were some changes in HttpPresentationManager and 
CachedFilePresentation from 3.1.1 and we would like to try change the 
source in EAF 6.5.1 and troubleshoot the problem. Is there some simple 
instruction to set up the environment and compile EAF on Windows from 
command console or from Enhydra Eclipse 3.0 IDE?

Thanks in advance for your help.

Best regards,
KC Lau.
