Subject Re: [users@httpd] issues downloading zip files
Date Sun, 03 Nov 2019 03:35:33 GMT
Hello,

No, it's not a hosted web site.
It is not being run from home on a cable/dsl connection.
I do not know if it's a hosted physical/virtual server, I'll say yes
for the purposes of this discussion.

This problem started last month, prior to that everything was working
fine. The files are not identical month to month, but they are nearly
so in file size, we're talking 100 megs or less.
I do not believe the firewall setup changed, I will inquire.

Issues, means that some not all users atempting to download the files
from the server weree successful, while others myself included were
not. I can only speak for myself with the problem that the file
stops/times out at approximately 64% of the total file download.

File sizes are between 60 megabytes and 100 megabytes max.

Older files archived are able to be downloaded without a problem.

I do not know what appears in the apache log files, again I'll have to
ask, these files are private, I was asked to help and as I myself am
clueless I threw this one to the list hoping for some suggestions some
ideas I didn't have.

I can speak to the admin and arrange some packet captures, see what
that tells us and write back with any new information/questions.

Thanks.
Dave.
