Daniel Doubleday commented on CASSANDRA-2868:
---------------------------------------------
Looks good to me. Guess cassandra should just disable the inspector for now
(probably make it jmx'able to start it manually)

> We have memory issues with long running servers. These have been confirmed by
> several users in the user list. That's why I report.
> The memory consumption of the cassandra java process increases steadily until
> it's killed by the os because of oom (with no swap)
> Our server is started with -Xmx3000M and running for around 23 days.
> pmap -x shows
> Total SST: 1961616 (mem mapped data and index files)
> Anon RSS: 6499640
> Total RSS: 8478376
> This shows that > 3G are 'overallocated'.
> We will use BRAF on one of our less important nodes to check wether it is
> related to mmap and report back.
