cron "c queue max run limit reached"

I have a server which has several timed "cron" tasks that must
complete. A few weeks back, a power failure occured and now these
cron jobs do not work. Two days ago, I turned on the cron job 'log'
and today the log is showing "c queue max run limit reached" I
looked for more info on this messgae and was suggested to check a line
in th cron's queuedefs. The original file did not have a "c." line so
cron will use default settings.

How can I completely remove the limits or find/fix my problem?
