I get the email below daily. I'm thinking it's ok to cat /dev/null the cma.log file?
I also think I might be able to do the same thing to stdout.old?
Anything else I should try other than the instructions?

This is an automated message from the MeetingPlace Express system with
hostname [meeting.afgrp.com] to inform you that disk space is low.
Details on where the problem is and how to resolve it are indicated below.
Low space in partition /. Percent used = [90].
The following files might cause trouble. However, inspect each one to make sure.
Look specifically for large files with old timestamps. Also, note that some of
the files indicated might have been previously mentioned. In this case, use the
prior instructions to handle these files rather than the instructions below.
If you are uncertain, contact Cisco TAC for confirmation/advice.
For the files below, use the following procedure to empty these files rather than
delete them outright.
1. For each file to be emptied do:
cat /dev/null > <filename>
2. After all files that you wish to empty have been emptied, do:
su // Enter 'root' password.
mpx_sys restart

In general, to free up disk space where it is uncertain exactly what files are in question,
do the following:
1. In general, go to places like /root, /mpxadmin, /tmp and do "ls -la" to look
for large files. If a file is large, old, and seems like some kind of log or
error file, it could be a candidate for deletion.
2. Generally files of type log (*.log), stderr, stdout, or txt (*.txt) are the
best candidates to look for. A good command to look for these types of
files with size of 10,000,000 bytes or larger is:
find / -name "<file type>" -exec ls -la {} ; | awk '{if( >=10000000) {print} }'
For example, to look for all log files 10,000,000 bytes or larger on
the entire system:
find / -name "*.log" -exec ls -la {} ; | awk '{if($5 >= 10000000) {print} }'
3. If you have a specific problem partition that you are trying to reduce size
for, do the following:
1. Find out the directory name of the top of the partition from "df".
2. "cd" to that location.
3. Then do: du -x -b --max-depth=1
4. Look for the directories that are really large.
5. Then "cd" into the worst subdirectory (or subdirectories).
6. Get a list of all large files from current directory location and lower:
(This example assumes 10,000,000 bytes and a check for .log files.
Note the starting location of '.' (current location) rather
than '/' (entire disk) ).
find . -name "*.log" -exec ls -la {} ; | awk '{if($5 >= 10000000) {print} }'
Complete output of the 'df' command:
