IIRC, DSS for internal pub-sub and G-Reg for resource subscriptions. We will lose some functionality of subscribing for topics and so forth, but with some testing we should be able to avoid leaks OOM errors. The lightweight code was a tremendous improvement for high load scenarios. But for very high loads even this was failing. We had some improvements suggested and integrated(?), based on high and low watermarks plus a persistent queue as well. IIRC, these improvements were never properly load tested and verified. Also, are we doing this for this release? This would involve quite a bit of work, IMO. > -- > *Afkham Azeez* > Director of Architecture; WSO2, Inc.; http://wso2.com > Member; Apache Software Foundation; http://www.apache.org/ > * <http://www.apache.org/>** > email: **[email protected]* <[email protected]>* cell: +94 77 3320919 > blog: **http://blog.afkham.org* <http://blog.afkham.org>* > twitter: **http://twitter.com/afkham_azeez*<http://twitter.com/afkham_azeez> > * > linked-in: **http://lk.linkedin.com/in/afkhamazeez* > * > * > *Lean .
