The autobuild test system (on sn-devel-144) has detected an intermittent failing test in 
the current master tree.

The autobuild log of the failure is available here:

The failure seems to be in the "samba-nt4" suite, whose build logs are available here:
The top commit at the time of the failure was:

    dsdb: Log the transaction duraton.
    This is not a general purpose profiling solution, but these JSON
    logs are already being generated and stored, so this is worth adding.
    This will allow administrators to identify long running
    transactions, and identify potential performance bottlenecks.
    This complements a similar patch set to log authentication duration.
