    Hi,
    I'm upgrading graphs from 4.1.5 to 4.5.2. I am currently experiencing the following problem with X-Ref.
    The first input contains a dataset with 400 columns (don't ask...), there are 388 rows of data. The second input contains a dataset with 4 columns, also 388 rows. The join is on the ID column (common to both datasets) and the output is emit 1:*, 2:* .

    So, this works on my 4.1.5 graphs on LAE Servers running on both Windows and Linux.
    It also works on the 4.5.2. server running on Windows.
    However, it fails when run on a 4.5.2. server running on Linux (64bit).

    Nothing appears in the error log, though hovering over the node gives me an 'Errors for Join' error.

    I can get the node to run by removing a number of columns from the 400 column dataset - which makes me think there is some threshold being reached somewhere.

    Has anyone else experienced this, or is it a known issue?

    regards
    Damien

    This is a known issue (PR 3575) and will be fixed in the next release of the LAE, 4.5.3, which will be available in early Q1 of 2012.
