From release 1.2.18 to 1.2.19 the following change has been done to file lib/poller.php:

    554c577,581
    < 		if ($remainder && $limit != '') {
    ---
    > 		$rows = db_fetch_cell('SELECT COUNT(local_data_id)
    > 			FROM poller_output');
    > 
    > 		/* to much records in poller_output, process in chunks */
    > 		if ($rows && $remainder) {

I believe there is something wrong with the new test:

if ($rows && $remainder) {

which make the poller to enter into an infinite loop.

On our installation I changed it back to the old test:

if ($remainder && $limit != '') {

and it fixed the problem.

I believe that was already addressed in #4460

@netniV You are right I should have written my comment directly in #4460. I close this issue.
