TCP connection not closed even after the association is aborted

[shoibahamed]

The PACS after sending images, does not release the association. Hence the "Network timeout" is triggered.
When the association is timed out and aborted by the scp, the TCP connection remains in the ESTAB state. And it will remain in the ESTAB state until the application is restarted

I see this error on the prod environment and the PACS is STENTOR. However, I could not reproduce on my local

New connections are opened for every association and they remain open and eventually and application hits maximum_associations and then rejects all other associations that are trying to be opened with the error message - "local limit exceeded"

Can you post your code, the anonymised output from debug_logger(), details of the production environment and which version of pynetdicom you're using?
