Forum OpenACS Development: Re: Found the issue in Maurizio's NaviServer on Windows: Problem serving large files

Hi Maurizio,

I've checked the "large file" issue from ]po[ on your unmodified OpenACS installer, and it behaves exactly the same. There is an issue in your NaviServer binary!

Here is what I tested, so you can reproduce:
- I use a (pretty) fresh Windows Server 2008R2 install as a base,
- Installed your original "Windows-OpenACS-5.9.0.exe" installer,
- Copied a "ext-all.js" file (1.4MB) into C:\naviserver\servers\openacs\packages\acs-admin\www and
- Tried to load the file via the browser from within the VMware: http://localhost:8000/acs-admin/ext-all.js

As a result, the browser shows the first part of the file, but then hangs. NSD.exe starts to consume 50% CPU (there are only two cores assigned to the VM).


Dear Frank,
my installer, my binary... or simply Naviserver's behaviour on Windows?

...and how about the unbalanced braces...

Does this issue shows up also in the binary generated by Gustaf (I mean when running ]project-open[, not OpenACS)?

If not we need to understand the differences, if yes... then we are facing some problems in Naviserver that show up only in particular cases, work loads...

Please, if you can, get the binary form Gustaf. Please do try those binaries a big file, load then ]project-open[ and then let's see if we are observing different or identical behaviours.

Thank you for your analysis,

Hi Maurizio,

Sorry if this "you" sounds personal when I refer to "your" installer. I'm just very happy that I was able to narrow down the error quickly.

Maurizio, could you please try to load a slightly larger file with your OpenACS on your master Windows installation and confirm that you can reproduce the issue?

I couldn't test yet, I don't have the binaries yet. Waiting for them eagerly 😊
