------------------------------------------------

Saw this again when running some tests. There were no other tests being run in parallel though.

> When I ran the below query along with similar such queries in parallel, I have seen it
fail randomly. Did not see this failure from sqlline when I ran this query alone.
> {code}
> select ws1.* from widestrings ws1 INNER JOIN (select str_var_null_empty from widestrings
where str_var_null_empty is not null and length(str_var_null_empty) <> 0 )ws2 on ws1.str_empty_null=ws2.str_var_null_empty
where ws1.str_empty_null is not null and length(ws1.str_empty_null) <> 0 and length(ws1.str_var_null_empty)
> 4995 and length(ws2.str_var_null_empty) > 4800;

> I attached the error log. Since the data is large, I did not attach it here
