9 In a cluster environment using Samba and ctdb it is critical
10 that locks on central ctdb-hosted databases like locking.tdb
11 are not held for long. With the current Samba architecture
12 it happens that Samba takes a lock and while holding that
13 lock makes file system calls into the shared cluster file
14 system. This option makes Samba warn if it detects that it
15 has held locks for the specified number of milliseconds. If
16 this happens, <emphasis>smbd</emphasis> will emit a debug level 0
