<para>
In a cluster environment using Samba and ctdb it is critical
that locks on central ctdb-hosted databases like locking.tdb
are not held for long. With the current Samba architecture
it happens that Samba takes a lock and while holding that
lock makes file system calls into the shared cluster file
system. This option makes Samba warn if it detects that it
has held locks for the specified number of milliseconds. If
this happens, <emphasis>smbd</emphasis> will emit a debug level 0
message into its logs and potentially into syslog. The most likely
reason for such a log message is that an operation of the cluster
file system Samba exports is taking longer than expected.
The messages are meant as a debugging aid for potential
cluster problems.

<para>The default value of 0 disables this logging.</para>
