Re: OutOfMemoryError due to TopicSubscription

[Ishitori]

I am not sure why it uses a bridge to destination feature. Is there another
way to configure it? (sysadmin did it that way, not me)

But I wonder is 6 bridges is really a high number? How many resources does
it take to support a separate advisory topic subs? Here is the full config:
