This sounds like the issue with the machine running out of memory and the Out of Memory killer actually killing one of the VMWare instances. My experience with this on a very good machine was that there was enough memory, but it was timing that was causing the issue. The machine did not respond quickly enough to the memory request and the OOM Killer then acted. How I solved my problem was to reserve more memory as unused with this memory variable: I have had issues with VMWare host server and running out of memory, maybe try setting this variable in sysctl.conf: vm.min_free_kbytes=65536 (that will maintain 64MB of free RAM and should allow for enough time to prevent OOM kills) signature.asc Description: OpenPGP digital signature ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] leap second

Would have loved to know that then ;-) We have 2 8-node clusters that runs many java applications, and many java applications on seperate servers. I went nuts when all java running servers cam to 100% cpu all at once ! The guy I spoke to at RedHat GSS at about 00:45 UTC baiscly told me to reboot the server, wich ended up rebooting our 2 clusters... Bad... But since computers all over the world crashed, our clients did understood that the problem was far lower than they beleived it... ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

You only need the file from internic if there are changes to the root servers, which IIRC happened once in the past few years, and can't wait until $distro updates bind. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
