12-Core MacPro (2013) kernel_task over 1200%
Yesterday someone asked me to install TeamViewer and share my Mac screen with them while on a conference call.
I shut down my Mac before sleeping and woke up to some major problem with my 12-core CPU in hyperdrive, and the system activity monitor showed my Mac kernel_task was at 1,200% and the fan spinning so fast it sounds like a 737 Max 8 fighting its on AI.
Seems all that great "screen sharing" of TeamViewer added some kernel extension (kext) to my Mac and just destroyed it. I have never seen a problem like this since I owned this 12-core MacPro.
Update: The same problem persists after doing a full restore from a backup before I installed TeamViewer, so my apologizes to TeamViewer.
So, I'm lucky I had a backup from two days ago and am now completely erasing my disk to restore from backup:
It started out with a system message that the recovery would take 88 hours, but now it down to 34 hours, LOL.
I guess TeamView is not designed for high end Macs with 12 cores ;

I installed 10.5 (Leopard) on my G4 733 Mhz (after minor tampering with the install package, just switched a boolean FALSE to TRUE).
Everything works fine after startup, but once I sleep the computer and wake it back up, kernel_task starts using at as much CPU runtime as it can, as in past 90%.... (0 Replies)

Hi bros,
CPU speed of Sun Sparc Enterprise T5140 in data sheet is 1200 Mhz. Why it shows in "prtdiag -v" command each thread just has speed at 1165 Mhz.
Thank you,

vxconfigbackupd
vxconfigbackupd(1M) vxconfigbackupd(1M) NAME
vxconfigbackupd - disk group configuration backup daemon SYNOPSIS
vxconfigbackupd [-l] DESCRIPTION
The vxconfigbackupd daemon automatically backs up information about a disk group's new configuration whenever the configuration is changed. OPTIONS
-l Logs backup daemon activities to the file /etc/vx/cbr/bkdaemonLog. FILES
/sbin/init.d/vxvm-recover Startup file for vxconfigbackupd. /etc/vx/cbr/bk/dgname.dgid/dgid.dginfo Location of backup file for disk group information. /etc/vx/cbr/bk/dgname.dgid/dgid.diskinfo Location of backup file for disk attributes. /etc/vx/cbr/bk/dgname.dgid/dgid.binconfig Location of backup file for binary configuration copy. /etc/vx/cbr/bk/dgname.dgid/dgid.cfgrec Location of backup file for configuration records in vxprint -m format. NOTES
The vxconfigbackup command can be used to back up a disk group's configuration manually at any desired time. The disk group configuration backup and restore utilities do not save any data in the public region. This includes file system or other application data that is configured within VxVM objects. When a disk group is destroyed, its configuration backup information (including the backup directory) is also removed. The only exception to this behavior is when the disk group is in the precommit state of restoration. The backup directory should be large enough to accommodate copies of all the currently imported disk groups. The minimum recommended size of the backup directory is P * (N + 1) megabytes, where P is the private region in megabytes (by default, 32MB), and N is the number of disk groups. The additional P megabytes is required to hold a temporary copy of the disk group configuration when a disk group is imported or a configuration change is made. The default backup directory is /etc/vx/cbr/bk. The location of the backup directory can be configured by using the vxconfigbackup -l backup_directory_path command. SEE ALSO
