Re: [Bigdata-developers] Errors in bulk load tests (regression)

[Martyn C. <ma...@sy...>]

A BufferOverflowException emanates from DiskOnlyStrategy, line 409 since 
it does not check if there is room in the buffer before putting the data.

This is supposedly guarded by the calling DiskOnlyStrategy.write that 
checks to see if the writeCache needs flushing in order to fit the data.

I see this error also from StressTestConcurrentUnisolatedIndices, so 
that's where I am focussing right now.
