Changing application name in template linked to many hosts generates message:

Application updated:
[...]
Application "hd302:Memory" updated
Application "hd369:Memory" updated
No host with with hostid=[10815]

There a few such hostsid in the message.

There is no "hostid" 10815 in DB "hosts" table:
> select * from hosts where hostid = 10815;
Empty set (0.00 sec)

There are records with "hostid" 10815 in the "applications" table:
> select * from applications where hostid = 10815;
-------------------------------------------+

-------------------------------------------+

-------------------------------------------+

How to manually fix the problem?

Is it enough to:
delete from applications where hostid = 10815;
?
