Dear Mulyadi,
Thank you for your response. And apologies for being impolite.
On AnonHugePages, I do not allocate them, some application is doing that in our cluster and I have no way to tell which application it is, unless I can hook up monitoring tools one each compute nodes that keeps track of which application is allocating huge pages. Not sure if I even know how to do that. Any hints will be helpful.
-regards!!
Prem

I am at a deadlock pulling my hairs and can't seem to figure out (http://lists.kernelnewbies.org/pipermail/kernelnewbies/2015-September/015111.html) how to reclaim the AnonHugePage allocations when only system services are running on them. Reboot is an option but too many nodes and this happening frequently i need to know an alternate way out.Any help is greatly appreciated.Regards,PremDear PremSorry that I can not promptly answer any question these days.My quick conclusion is that, since you said you alocate huge page above, then I guess huge page has different reclaim policy, that's why it might not be released when your application terminated. maybe you forgot to explicitly release them?All in all, I appreciate you ask my help, but next time please make sure that person is inviting you for direct discussion first, so you won't be considered as impolite.
