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:

    ctdb: Adding memory pool for queue callback
    The received packet is copied into a newly allocated memory chunk for further
    processing by the assigned callback. Once this is done, the memory is free'd.
    This is repeated for each received packet making the memory allocation / free
    an expensive task. To optimize this process, a memory pool is defined which
    is sized identically to the queue's buffer.
    During tests it could be seen that more than 95% of all messages were sized
    below the standard buffer_size of 1k.
