Cron syslog issue

[manjunath.nm89]

I have written a custom cron. This cron executes a rake task every 5 minutes. I also log the trace of this execution in a file locally on my server. The whole process seems to execute seamlessly every 5 minutes, but then it seems to log it in /var/log/syslog. I investigated on the syslog and found that system's critical errors, and other cron issues are logged in syslog. Has anybody faced this kind of an issue ?
