The reason for the failure seems to be in default configuration of PAM
for SSH.
If I understand correctly, PAM is configured to enforce session keys revocation
upon termination of parent SSHD process:
--- /etc/pam.d/sshd ---
...
# Create a new session keyring.
session optional pam_keyinit.so force revoke
...
---
Some environments connect using ssh and then "detach" from it, which
probably causes session key termination.
As a workaround I propose commenting out "force revoke" in
/etc/pam.d/sshd.
Note: There might be security related repercussions!
