CPU Utilization issue

I am working in C,C++ Telecom Provisioning application which is running in LINUX Red Hat Server. My application is running with several process like scmng,scspf, etc..
We have Log level setting for each process like 0,5,10,20.
If I set the FLOW level as 0, then it will not print any log info in log file.
If I set the FLOW level as 10, then it will just print only log info in log file.
If I set the FLOW level as 20, then it will print log plus time stamp in log file.

The issue is, one of the above process "scspf"(It is child process having 40 process) is utilizing the CPU as 100% when ever we set the FLOW level as 20.
If we set flow level to 0, then the CPU Utilization is 3 to 10 percent only.

In IBM AIX, it is not utilizing the CPU as 100% whenever we set the FLOW log as 20.

Please advice what is the root cause of this issue in Red Hat Server and how to rectify.

NAME
chkfontpath - simple interface for adding, removing, and listing directories in the X font server's path SYNOPSIS
chkfontpath [-lqfh] [-a name of directory to add] [-r name of directory to remove] DESCRIPTION
chkfontpath provides a simple method of configuring the directories contained in the X font server's path. As of Red Hat 6.0, all fonts in X are served via this separate font server process, not through the main X server process. This speeds up font rendering, and also allows use of font servers which are not running on the local host. chkfontpath is mainly used by rpm in its %post and %postun sections to add and remove new directories to the server's config file at installation and de-installation time of packages containing fonts. -a, --add=name of directory to add Add a directory to the font path. -r, --remove=name of directory to remove Remove a directory from the font path. -l, --list List all directories in the font path. -q, --quiet Quiet operation; don't display any output to the screen, even when there is an error during operation. -f, --first Requires usage of the add command; puts the specified directory first in the font path, rather than last. -h, --help Show detailed help on the command line. When directories are added to the path, some sanity checking is performed to make sure you are not adding a directory without the file fonts.dir contained in it, which the server needs to be able to render fonts properly. When a path is succesfully added or removed, the xfs process is restarted if it is currently running. RETURN CODES
chkfontpath returns 0 on success, or 1 on error. FILES
/etc/X11/fs/config Configuration file for the X font server (xfs). SEE ALSO
xfs(1),fslsfonts(1) AUTHOR
