I have a strange problem on one Mac: when doing selects that return large result sets (> 10.000 rows), the sql client on that machine hangs. It does not return anything and just waits. All other machines can run the query without any problem. Even more strange: that Mac can do that query on the staging mysql without any problems. It only has problems with the live mysql server instance.
Is there any advice what I should check? The my.cnf is the same as the config on the other macs.
