--- Comment From rjbr...@us.ibm.com 2019-08-14 15:40 EDT--- Its the same symptom between the huge dumps and the later kdumps. We opened with the huge dumps because thats what we had at the time, use the kdumps if they are more consumable. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1831899 Title: Kernel Oops 3b in libc-2.23 unable to handle pointer dereference in kernel virtual address space To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-z-systems/+bug/1831899/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

--- Comment From rjbr...@us.ibm.com 2019-08-14 11:14 EDT--- the 2 vmdump generated dumps were already converted during the read into the linux file. are you able to get to the kdump dumps here: https://ibm.box.com/s/g2ecltl3o2be54iksp7du4v9lk0rnp3m Those may be easier to parse than the vmdump generated dumps. The docker container images are probably part of a Jenkins build pipeline that is building s390x binaries for other IBM teams. We don't have logs on what they were doing at the time of failure. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1831899 Title: Kernel Oops 3b in libc-2.23 unable to handle pointer dereference in kernel virtual address space To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-z-systems/+bug/1831899/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

--- Comment From heinz-werner_se...@de.ibm.com 2019-06-18 03:36 EDT--- The dumps are not z/VM dumps. All can be analysed by Linux tools... --- Comment From heinz-werner_se...@de.ibm.com 2019-06-18 03:38 EDT--- The comend "z/VM took a VMDUMP and IPLd" is not from J. Brenneman Update informaion: Linux Kernel is abending with a kernel oops , and z/VM OpsManager watching the virual machine console automatically ran VMDUMP of the virtual machine to dump the whole Linux virtual machine memory to spool. I pulled the 2 large dumps out of spool with the linux 'vmur receive' command with the -c argument to convert VMDUMP format to Linux kdump format. those two large dumps are linux dumps and should be able to be processed with linux tools. I later enabled linux kdump and that gathered a couple additional dumps on subsequent abends with the same symptom and I've added those to box as well, so both VMDUMP originated huge dumps and more reasonably sized Linux Kdumps are referenced in box links in the BZ. There is no z/VM CP development based analysis required as far as I can tell - this is entirely a Linux kernel and glibc issue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1831899 Title: Kernel Oops 3b in libc-2.23 unable to handle pointer dereference in kernel virtual address space To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-z-systems/+bug/1831899/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

--- Comment From rjbr...@us.ibm.com 2019-06-06 11:59 EDT--- Ive got two dumps: dump1 : http://pokgsa.ibm.com/~rjbrenn/public/dump.190529.1324.gz dump2 : http://pokgsa.ibm.com/~rjbrenn/public/dump.190529.2120.gz but they are over 2GB each because they are VMDUMP not kdump. Is there a SFTP server I can use to make them available to you ?
