Hi Guys, My users are reporting some issues with memory on our lustre 1.8.1 clients. It looks like when they submit a single job at a time the run time was about 4.5 minutes. However, when they ran multiple jobs (10 or less) on a client with 192GB of memory on a single node the run time for each job was exceeding 3-4X the run time for the single process. They also noticed that the swap space

Starting with 3.7 rc1, my workstation seems to loose ram. Up until (and including) 3.6, used-(buffers+cached) was roughly the same as sum(rss) (taking shared into account). Now there is an approx 6G gap. When the box first starts, it is clearly less swappy than with <= 3.6; I can''t tell whether that is related. The reduced swappiness persists. It seems to get worse when I update

Hi, I'm using linux 2.6.21.5 and our kernel is freeze. The problem is, if I create a Software bridge using $brctl command. and add two interfaces say, eth0.0 and eth0.1 using $brctl addbr br-lan $brctl addif br-lan eth0.0 $brctl addif br-lan eth0.1 and when i send traffic from a host connected to one port to host connected at other end, soon all the memory is dried up and and kernel

Hello, I work in a hosting company, we have tens of Xen dom0 running just fine, but unfortunately we do have a few that get out of control. Reported behaviour : - dom0 uses more and more memory - no process can be found using that memory - at some point, oom killer kicks in, and kills everything, until even ssh the box becomes hard - when there is really no more process to kill, it crashes
