Recently I setup Zimbra 5.0.10 GA on my RHEL5 server. Both software and operating system are 64 bits. The server has 4GB memory.
I notice that the first day I bring the server into production...the memory usage is 46% of the total physical memory.
Second day, the memory usage is 51% of the total physical memory. And today is third day, the memory usage is 56% of the total physical memory.
I feel weird why the memory usage keep increase!??? I'm worry that within a week I will face memory problem.
