Dobrý den,
instalace:
Proxmox 6.2.11  - Turnkey Fileserver - Samba server
systém je aktualizovaný Samba 4.9.5 
Vše mám nastavené a funkční, Samba po cca 35 minutách spadne, pokud jí restartuji tak opět běží, v logu je toto:

Máte někdo nějaký nápad co s tím?
Takto je to zcela nepoužitelné. Prohledal jsem web a našel jsem nějaké rady na podobné problémy v nastavení 
smb.conf , ale nic nepomohlo.
Díky za rady
Martin
