So, I have a farm of machines runnign 7.1/amd64, all of which have 16 gig of memory in them. This afternoon, as an experiment, I altered loader.conf to have these two lines in it: vm.kmem_size="1536M" vm.kmem_size_max="1536M" This is what I do on machines running ZFS - these machines are not, however running ZFS, and do not have the zfs module loaded. I just wanted to see if

Hello! I was trying to build OpenOffice using all of my 4 CPUs. To be able to do other work on the machine comfortably, I ran the build under nice, and assigned real-time priority to the two Xorg processes. The build started at about 23:10 last night, and hung at 23:46. The procstat output for the make's process group is: PID PPID PGID SID TSID THR LOGIN WCHAN EMUL

I'm running a few servers sitting on top of a NetAPP file server ? everything runs great, but periodically I'm getting: nfs_getpages: error 13 vm_fault: pager read error, pid 11355 (https) errors on my screen ? not always same pid ? the annoying part is that it seems to always affect the same jail that is running .. if I shutdown all jails on that physical server, everything shuts down
