Pt-table-checksum waiting

Hi,
i have a problem:
“pt-table-checksum --nocheck-binlog-format --fail-on-stopped-replica”
runs good and break if the slave not running
(“Replica xxx is stopped. Waiting.”) but if i use the “–quiet” option
(i need only the DIFFs at this) the program waits at this point for ever:
“Checking if all tables can be checksummed …
Starting checksum …”

Any ideas?
Thanks!

Hi, are you sure the program is not actively working? check with show process list to see if you can spot some checksum going on.
The --quiet option should only suppress printing information but not alter the process in any other way.
