Patch Name: PHKL_7118 Patch Description: s700 10.09 [Lev36] system hang with audit on Creation Date: 96/04/16 Post Date: 96/04/24 Hardware Platforms - OS Releases: s700: 10.09 Products: N/A Filesets: OS-Core.CORE-KRN ProgSupport.C-INC BLS.BLS-CORE Automatic Reboot?: Yes Status: General Release Critical: Yes PHKL_7118: HANG Path Name: /hp-ux_patches/s700/10.X/PHKL_7118 Symptoms: PHKL_7118: * System hangs when audit on (no memory space) Defect Description: PHKL_7118: * The problem is caused by the method used to account for audit space. When construct an audit record, it checks whether the audit record is selected based on certain criteria, performing copyin()'s and other activites that may block a process. Since many processes may proceed through the space usage check, when all of these processes put to sleep and eventually wakeup, they push the space usage way past the configured limit and have eaten much memory space. When this occured, the auditd process was unable to run as its text could not be paged in (no room).

Back up your system before installing a patch. 2. Login as root. 3. Copy the patch to the /tmp directory. 4. Move to the /tmp directory and unshar the patch: cd /tmp sh PHKL_7118 5a. For a standalone system, run swinstall to install the patch: swinstall -x autoreboot=true -x match_target=true \ -s /tmp/PHKL_7118.depot 5b. For a homogeneous NFS Diskless cluster run swcluster on the server to install the patch on the server and the clients: swcluster -i -b This will invoke swcluster in the interactive mode and force all clients to be shut down. WARNING: All cluster clients must be shut down prior to the patch installation. Installing the patch while the clients are booted is unsupported and can lead to serious problems. The swcluster command will invoke an swinstall session in which you must specify: alternate root path - default is /export/shared_root/OS_700 source depot path - /tmp/PHKL_7118.depot To complete the installation, select the patch by choosing "Actions -> Match What Target Has" and then "Actions -> Install" from the Menubar. 5c. For a heterogeneous NFS Diskless cluster: - run swinstall on the server as in step 5a to install the patch on the cluster server. - run swcluster on the server as in step 5b to install the patch on the cluster clients. The cluster clients must be shut down as described in step 5b. By default swinstall will archive the original software in /var/adm/sw/patch/PHKL_7118. If you do not wish to retain a copy of the original software, you can create an empty file named /var/adm/sw/patch/PATCH_NOSAVE. Warning: If this file exists when a patch is installed, the patch cannot be deinstalled. Please be careful when using this feature. It is recommended that you move the PHKL_7118.text file to /var/adm/sw/patch for future reference. To put this patch on a magnetic tape and install from the tape drive, use the command: dd if=/tmp/PHKL_7118.depot of=/dev/rmt/0m bs=2k Special Installation Instructions: None
