Hi all, I have a 16 process/64GB RAM compute node running Grizzly with some odd memory usage behavior. The node is currently running 17 lightly used VMs. root at test1:~/scripts# free -m total used free shared buffers cached Mem: 64429 48742 15687 0 0 28479 -/+ buffers/cache: 20263 44166 Swap: 4093 4026 67 As you can see I have over 15GB free (44 if you remove cached memory!) yet the swap space is almost completely full. Any idea what might be going on? Thanks, Sam -------------- next part -------------- An HTML attachment was scrubbed...
