Dear Maintainer,

openigtlink package is pretty old and obsolete on Debian, we should consider update the package to a recent version.
Current version contains a bug already fixed on upstream:

On Linux OS, only a shutdown() was performed on socket descriptors, leading to an undestroyed socket.

When creating a server, activate it and then deactivate it, afterwards, the socket could not be activated again.

To fix this newest versions of openigtlink also call close() on socket descriptor.

See the upstream issue from 2017: https://github.com/openigtlink/OpenIGTLink/issues/133

We believe that the bug you reported is fixed in the latest version of
openigtlink, which is due to be installed in the Debian FTP archive.

A summary of the changes between this version and the previous one is
attached.

Thank you for reporting the bug, which will now be closed.  If you
have further comments please address them to 1010511@bugs.debian.org,
and the maintainer will reopen the bug report if appropriate.
