That's expected...ldm won't be allowed to overwrite the logs.

Did you remove the logs at this point? Again...ldm won't be allowed to
remove root owned files.



If you have an rc.local entry make sure it has:

/bin/su - ldm

preceding any command, or it will be run by root. I've had that issue
with auto starts when a host is rebooted. That might be the originating
source of the issue...maybe. Stuff like that can be frustrating.




Also of relevance - from syslog itself:
Log files MUST exist prior to the start of syslogd.



I don't recall seeing this behavior before, but a poke around a newer
host I setup recently I see some noaaport logs with root:ldm
permissions...which is wrong. It's not receiving noaaport data, so
they're empty but it's a curious issue. My main logs (ldmd.log and
metrics.txt ) are just fine however. Seems like there's a quirk somewhere.


I'm willing to bet the nuance is the newest ldm (6.9.x) adding the var/
directory...Is ~ldm/logs a directory or symbolic link to ~ldm/var/logs ?

Hope something there helps.
