rc.log logging port open errors

[John Carver]

I traced a full / filesystem to the /etc/rc.log continually logging "Port /dev/tty0p1 Open Error" errors. This tty device is for the UPS Manager. I unconfigured this in SAM, commented out the entries in /etc/inittab and issued "init q" to re-read and commented out the lines in /etc/ups_conf. The errors are still being logged. I may be attacking this from the wrong angle. What am I missing?

Typically the /etc/rc.log is used as output for the /sbin/rc script. ( unless your inittab specifically redirects output for your UPs daemon.

So I would suspect there may be an rc script in /sbin/init.d/* that is run during boot and holding open the /etc/rc.log.

If you have losf, use it to see what PID has the rc.log file open. Maybe now that you have disabled it you still need to kill it.

I don't have lsof on this server so I ran fuser instead on the rc.log file. There were a number a processes holding the file open including the NFS processes. I did find a process that belonged to a third party power monitor that was still running. I went and killed the process and removed the start and stop scripts since I no longer need it. The errors have stopped logging. Thanks for the second set of eyes on the problem.
