Problems after upgrading from Iris for Health 2023.1.2 (450U) to 2024.1 (267_2U)

After upgrading we had 2 major problems with the new version:

- Resending messages adds blank lines.
Because we have many HL7 processes, we regulary have to resend messages if there is an outage of a server we connect with.

- IIS recycling causes webgateway connection problems, after change from PWS to IIS.
At unexpected times a connection can no longer be made.
The strange thing is that it does not occur with every recycle of the application pool.
Setting the password again in csp.ini usually works, but not always, which is of course a major problem.
I was wondering if there is a server component like MAC address is used for hashing the password which can cause this?

Due to these problems we had to rollback to the old version.

Will these problems be fixed in version 2024.1 and when is this version to be expected?
