sshd trouble right out of the box :(

On a fresh Vultr.com instance running FreeBSD 14.3-RELEASE, sshd
periodically (ie. every few hours) logs the following message, and
then dies. So I have to restart the server to get in :eyeroll:

    sshd[1015]: fatal: pack_hostkeys: serialize hostkey private:
    string is too large

Ducking finds nothing relevant. Anyone, please?
