Description

It's apparent in our production environment that HS2 leaks sessions, which at least contributed to memory leaks in HS2. We further found that idle HS2 sessions rarely get timed out and the number of live session keeps increasing as time goes on. Eventually, HS2 becomes irresponsive and demands a restart.

Investigation shows that session idle timeout doesn't work appropriately.
