TCP Port re-use V91 and above

[DK]

I have started to have issues with some webservers with V91 and above.  I have found that after a connection is closed the browser will initiate a new connection using the same source port.  This is leading to issues with firewall dropping the SYN due to its time-wait configuration and in some situations where the server has closed the connection and the connection on the server is in the 2MSL time wait.

The source ports affect by this are all low ephemeral 1024-1100... etc

has anyone else noticed this

What is the OS on which the browser is running?

Please file an issue at crbug.com with information about the platform you are running and if possible a Wireshark trace.

Please reply to this thread with the issue number so I can make sure it is routed correctly.

Thanks for your replies.  I logged a bug 

Issue 1224740

After further research we have found that our systems are not using the standard dynamic port ranges, ours are using 1024-65535.

When we set them to standard 49152-65535 we do not see the tcp port reuse
