Re: Server Missbehaving, why?

It depends on it's load balancing solution My guess is that the load  

balancer is running out of memory and eventually looses information  

on older connections and your packets get redirected to a new server  

which doesn't know anything about you or the load balancer just  

terminates the connection itself.

I haven't seen the same issue with my Foundry switches.

Hi group.

Not that I would be able to solve it, but I'd like to know.
Background:
One of my homepages is hosted on servage.net (www.ebaman.com)
They use loadbalanced clustered apache-servers if I understand thing
correctly.

Now the problem is as follows.
When uploading large files (above some 50-100megs) to the server using

HTTP-PUT method, the server is resetting the connection after a  

while, and

the upload fails. The server (I assume) is sending a TCP-RST.

When downloading using HTTP-GET, the server sometimes sends a TCP- 

FIN after

a while, the time varies, so you can get somewhere between 4 to 90%  

of the

file before the conn is closed.

I'm using PHP to generate the pages.

Here is the entries in my .htaccess
php_value upload_max_filesize 700M
php_value post_max_size 710M
php_value memory_limit 720M
php_value session.gc_maxlifetime 100000
php_value max_execution_time 100000
php_value max_input_time 100000
LimitRequestBody 2147483646

This should be enough as far as I understand.

So the question is, Why is apache terminating file-transfers
