Hi @sulfred , there are 3 spool quotas to consider:
- the individual queue spool quota;
- the message-vpn spool quota;
- the system spool quota.
Exceeding any of these will mean your message is rejected. You seem to have received a “Router limit exceeded” error which points to the system spool quota being exceeded. To check, open PubSub+ manager. Before you go in to the Message-VPN screen, pick “Guaranteed Messaging” from the left hand menu, then pick settings from the tabs at the top. This will get you to the system level spool settings, and you can see the system level quota there.
