Samba has released version 4.23.6, which includes crucial bug fixes aimed at enhancing performance for home and small office networks. This update addresses memory leaks in the rpc_spoolss service and improves lease handling for more reliable file locks when clients disconnect. Users upgrading to this version should back up their custom configuration files and follow their distribution's package manager for a safe installation process. Additionally, some legacy clients may encounter "invalid lease" messages after the update, but refreshing their cached credentials typically resolves this issue

Samba 4.23.6 Update: Fixing Memory Leaks and Improving File Sharing

Samba 4.23.6 has been released with several important bug fixes that improve performance for home and small office networks. The update addresses memory leaks in the rpc_spoolss service, which caused print servers to hang after a sudden crash, as well as lease handling issues that led to unreliable file locks when clients disconnected abruptly. Upgrading to 4.23.6 should resolve common problems such as shared printers stopping response and "file still in use" errors popping up all the time.
