Test again,It is my mistake.
The new subscriber do not receive old pending msg after JBM reboot.
But,the records in db does not deleted,my JBM_MSG_REF has more than 50,000 records.
you can manually deleted them by yourself if you don't need them.
Thanks for reply.
Any plan to delete the out-of-date msg automatic if no durable subscriber?
The system will slow down when the records increasing in huge messages situation.
Yes, this is the way JBM 2.0 already work (see JIRA).
JBM 1.x is in maintenance only mode, we're not planning on backporting new features.
