samba - Mar 2021 - Intermittent problems with roaming profiles

Hi all
Not sure if this is samba related at all, but I have an issue with roaming
profiles, specifically for a client that uses two computers, a laptop and a
workstation, running on the same account in a domain with a Samba
4.11-6.??Clients computers are both Windows 10, fully updated.

He get the dreaded 1521, Unable to access profile during logon a couple of times
per week. Sometimes logging off works, sometimes a full restart is required. I
have read uncountable postings regarding profile problems, and some posts talks
about pending oplocks, files not closed properly on the server. Most of these
post probably talks about Windows file servers, not Samba. Is anyone aware of
similar issues on Samba?

I doubt that permissions is involved since that should be consistent. Anyway,
the permissions on the profile folder is this

administrator at hp-srv03:~$ sudo getfacl /share2/profiles
[sudo] password for administrator:
getfacl: Removing leading '/' from absolute path names
# file: share2/profiles
# owner: administrator
# group: root
user::rwx
user:administrator:rwx
group::---
group:root:---
group:domain\040admins:rwx
group:NT\040Authority\\system:rwx
group:domain\040users:rwx
mask::rwx
other::---
default:user::rwx

default:group::---
default:group:root:---
default:group:domain\040admins:rwx
default:group:NT\040Authority\\system:rwx
default:mask::rwx

Users get a message about 'tempoary profile' usage? Linux (not samba)
default socket reapup are a bit lazy, try to add to [globals] in your
smb.conf:

	# Performance.
	# TCP_NODELAY, che si tova in letteratura, ? il default da samba 2.0. Per
scrupolo lo lascio.
	# I default per TCP_KEEPIDLE, TCP_KEEPCNT e TCP_KEEPINTVL sono rispettivamente
in
/proc/sys/net/ipv4/{tcp_keepalive_time,tcp_keepalive_probes,tcp_keepalive_intvl}.
	# Modifico questi valori per evitare lock sui file.
	#
	socket options = TCP_NODELAY TCP_KEEPIDLE=240 TCP_KEEPCNT=4 TCP_KEEPINTVL=15
