----------------------------------------
I'm 5 for 5 so far.
> [C++][R] Arrow Hangs reading binary file generated by C#
> --------------------------------------------------------
>
> Key: ARROW-6682
> URL: https://issues.apache.org/jira/browse/ARROW-6682
> Project: Apache Arrow
> Issue Type: Bug
> Components: C++, R
> Affects Versions: 0.14.1
> Reporter: Anthony Abate
> Priority: Major
> Attachments: Generated_4000Batch_50Columns_100Rows_PerBatch.rar
>
>
> I get random hangs on arrow_read in R (windows) when using a very large file
> (10-12gb). (the file has 37 columns)
> I have memory dumps - All threads seem to be in wait handles.
> Are there debug symbols somewhere?
> Is there a way to get the C++ code to produce diagnostic logging from R?
>
> *UPDATE:* it seems that the hangs are not related to file size, row counts,
> or # of record batches, but rather the number of *columns*
