[LDM #BBO-672523]: LDM at NOAA



Russ,

It odd that reverting to the previous kernel didn't fix the problem. Were there 
latent patches to the previous kernel that the LDM didn't see until the system 
was rebooted with that kernel?

The error messages indicate that the start-up procedure for the LDM failed 
because
    1. it couldn't rotate its log files (i.e., rename them and create a new 
empty one); because
    2. it couldn't get the process-ID (PID) of the system logging daemon; 
because
    3. hupsyslog(1) couldn't open the file that should have contained that PID 
(/var/run/syslog.pid).

Does the file "/var/run/syslog.pid" exist? If so, what are its protections?

Is the hupsyslog(1) LDM utility owned by root and is it setuid?

Is the same system logging daemon as before being used (e.g., "syslogd", 
"rsyslogd")?

Was the system logging daemon running when the attempt to start the LDM was 
made?

Is the PID of the system logging daemon put into the file "/var/run/syslog.pid"?

Regards,
Steve Emmerson
