[Lustre-discuss] Memory (?) problem with 1.8.1

[Nirmal Seenu]

We face this problem on the Lustre servers on our cluster with GigE 
network. We found that increasing the following value in 
/etc/sysctl.conf forces the kswapd to kick in a lot earlier and prevent 
the scenario that you are talking about. Our servers have only 8GB 
memory, you might want to bump it up to 2GB or even 4GB with 32GB system 
memory.

# Control the min_free_kbytes
vm.min_free_kbytes = 1048576

Hope this helps.
