Odysseas and Sylvain, Reason for sure is that RAM from point of view of OS is exhausted. OS returned 0 (NULL) as result of data allocation.
Probably you have some restrictions on memory allocation or merely other applications are running in parallel. We will avoid such exceptions in 2.1 as Sylvain suggested , if we do not have enough memory we will push data to the disk and will not throw OOM to the client.
