Description:
In a execute(commit, ignore-error) where some operations
succeded and some failed, there is a race-condition
which might cause ndbapi to incorrectly report 4011 (internal error)
as it gets confused.

this is seen by pushbuild rpl_ndb.rpl_ndb_idempotent

the bug is "easy" to trigger using multi-threaded ndbmtd,
but can also be provoked using a "big" cluster (i got it with 8 nodes)

How to repeat:
will write clever test prg

Suggested fix:
.

        ndbapi could get confused if tckeyref/tckeyconf came in not common
          order

Documented in the NDB 6.2.16 and 6.3.16 changelogs as follows:

        When some operations succeeded and some failed following a call to
        NdbTransaction::execute(Commit, AO_IgnoreOnError), a race condition
        could cause spurious occurrences of NDB API Error 4011 (internal error).
