Hi,
I'm using AWS for developping a Web application but I got some problems
during my tests.
Actually whenever I launch the application (for instance on port 8000) I
test somes pages, everything is fine. But I have to make a fast
modification (let's say, about 1 minute) and then I try to launch again,
I got the following error message:
raised AWS.NET.SOCKET_ERROR : Bind : [98] Address already in use
The point is, there is still TIME_WAIT after the shutdown of the server.
How can I be sure that the connection are all properly closed before
ending the server?
I'm using the shutdown method of AWS, but it looks like it's not enough.
thanks by adance,
Sebastien

This is expected and OS dependent. There is no such problem on Windows
for example. This is a security issue AFAIK. It is not possible to reuse
an address for some time after a process has been using it.
For production it is better.
While developing it is possible to set "reuse_address" to 'true" either
using a .ini file or dynamically into a config object.
Note that all AWS questions are best addressed into the AWS's mailing-list.
Pascal.

We agree

Thanks, I know where it comes from, but I thought it could have a way
from the server to close properly the connection whithout caring what
the client is doing, but there is not, and it's clearly an OS issue. I
think I have to read agin my network lesson ;-)

Hum not sure we understand each other. I mean from the server side you
can set into your .ini file (look into the AWS documentation how to use
one):
reuse_address true
