["Will Jones (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ARROW-16423?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17530264#comment-17530264 ] 

Will Jones commented on ARROW-16423:
------------------------------------

Hi Andrew, could you provide the output of:

{code:R}
sessionInfo()
arrowInfo()
{code}

I tried this locally on 7.0.0 and dev branch (soon to be released) on MacOS, with both {{options(use_thread = ...)}} set to false and true, and didn't get any error.

> Trying to do an inner join style filter on an open_dataset, and R crashes, but not reliably the first time. Sometimes takes a couple of tries until it does.
