Description:
Error 899 can occur during high insert/delete-load
The problem is that LCP is not syncronized between the nodes,
  and the LCP snapshot prevents deleted ROWIDs to reused directly
  (even if time when they are not reused should be short...
   possibly it's higher if running with low disk-checkpoint-speed)

However, the LCP-snapshot is only needed for DD-tables

So the (forth-coming) patch removes it from MM-tables.

  ndb - bug#34033

    removing possibility of spurious 899 on MM-tables

pushed to 51-ndb, telco-*

Documented bugfix for 5.1.23-ndb-6.3.8 as follows:

      
        High numbers of insert operations, delete operations, or both
        could cause NDB error 899 (Rowid
        already allocated) to occur unnecessarily.        
      
Left bug in Patch Queued status pending further merges.

Also documented for 5.1.23-ndb-6.2.11; left status unchanged.

Pushed into 5.1.24-rc
