I just mention this because apparently having mixed CPU architecture in the environment can cause this (not applicable in my case). I have updated / uninstalled / reinstalled the SMB client - nothing changes. Can this be fixed? I am able to connect to SMB servers (Windows VMs) with other server (Ubuntu, PhotonOS, Windows), just not this RHEL 8.7 server. journalctl | grep smbclient Mar 01 14:30:45 RHEL-8-Salt-Master systemd-coredump: Process 4025418 (smbclient) of user 0 dumped core.
