...ed to: Linux 2.6.18-194.17.1.el5 #1 SMP Wed Sep 29 12:50:31 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux I'm aware that there are later updates that patch couple more security bugs. Here is an issue I run with 2.6.18-194.17.1 and am asking if anyone hits that kernel bug. Here are the symptoms: 1) kswapd1 running at 100%, there are not much paging 2) when i logged in, root can't kill -9 ANY processes 3) memory is used up, swap is probably only used up for couple hundred MBs at most (Swap space has couple Gig available) I saw in the logs: kernel: INFO: task sadc:23936 blocked for more than 120 s...

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
