Java consumes many RAMs and CPUs!
As i know, mailboxd_java_heap_memory_percent only can be allocated to 2GB RAM and I have set it to <= 2 GB RAM. However, i see that java always consumes many RAMs and CPUs (99.9% CPU and 30.4% RAM) and it seems to not release RAM and CPU . My server have 8 GB RAM and i'm on zcs 5.0.5. Although i see that RAM is still free 1 GB but my zimbra is overloaded. I think that java have used > 2 GB RAM and it can't allocate more RAM because i set "mailboxd_java_heap_memory_percent" to <=2GB. If i set "mailboxd_java_heap_memory_percent" to more 2 GB RAM, mailboxd can't start (Bug 21348).
Please for give me an advice.
