[Ocfs2-users] out of memory problem concerning 64-bits?

[Michał Wilkowski]

Hello,
we are currently running in production the system based on Redhat 
Enterprise Linux 4 Update 3, ver. 32-bits. We are periodically 
encountering an OOM-killer problem. Problem was discussed in previous posts.

I have a question: does it concern only 32-bits systems or 64-bits as well?
On 32-bits system OCFS2 driver consumes Low Memory (only ~900 MB) and 
therefore causes oom-kills. What about 64-bits systems? Does it consume 
all memory available for system (in my case: 8 GB)  and therefore it 
takes much longer to encounter oom-kills?

It is a very important issue for me and a response would be greatly 
appreciated.
