System log question

[nealt]

My Mac seems to be running normally. However I notice in the system log hundreds of entries like:

Sep 30 08:59:59 nealnt.local UserEventAgent[181]: Could not get event name for stream/token: com.apple.time/406: 0x3: No such process

Sep 30 08:27:11 nealnt kernel[0]: Sandbox: sandboxd(54321) deny mach-lookup com.apple.coresymbolicationd


Sep 30 02:00:16 nealnt.local sandboxd[52316] ([7422]): Mail(7422) deny file-read-data /Library/Preferences/com.apple.mail.plist

Probably there is no cause for concern. But they probably occupy cpu time. Also it makes using the system log as a troubleshooting tool very difficult.

Any comments on this?

Mac Pro, OS X Mountain Lion (10.8.2)

Surely someone has knowledge about this. I would appreciate any info.

Those are sandbox errors.

Looks like you're not the only one having those with Mail.app in 10.8. Some of the ideas in that link may work for you; namely try renaming com.apple.mail.plist to com.apple.mail.plist.bak and the same for com.apple.coresymbolicationd. Plus clearing the caches with e.g. OnyX would not be a bad idea.

This would probably also help understand sandboxing and the errors you see http://eternalstorms.wordpress.com/...sandbox-and-its-implications-on-applications/
