503 Spool Over Quota. Queue or Topic endpoint limit exceeded

Interesting… I didn’t know that even some of the terminology in Manager is remapped when deployed as SAP AEM. EDIT: it looks like the term “Silent” was added to more recent Solace brokers as well… I guess Nick and I are a bit out of date!

Yeah, “Silent” will make your q1 queue into essentially a “best effort” queue, and that it will be fully Guaranteed with ACKs and everything until it is full, and then it’ll just lose new messages while its spool is over quota.
