Avro consumes all memory on box

[web user]

Hi,

I'm doing the following:

from avro.datafile import DataFileReader
from avro.datafile import DataFileWriter
from avro.io import DatumReader
from avro.io import DatumWriter

def OpenAvroFileToRead(avro_filename):
   DataFileReader(open(avro_filename, 'r'), DatumReader())


with OpenAvroFileToRead(avro_filename) as reader:
   for r in reader:
       ....

I have an avro file which is only 500 bytes. I think there is a data
structure in there which is null or empty.

I put in print statements before and after "for r in reader". On the
instruction, for r in reader it consumes about 400Gigs of memory before I
have to kill the process.

That is 400Gigs! Ihave 1TB on my server. I have tried this with 1.6.1 and
1.7.1 and 1.7.7 and get the same behavior on all three versions.

Any ideas on what is causing this?

Regards,
