I am suprised that more people have not encountered this problem if it is simply exhibited with frequently-executed jobs. I will try running cron with some debugging options enabled (-x proc and maybe some others), and see if I can duplicate this; if anyone else wants to do so also, that's fine :-) It may be helpful to obtain a core dump and executable image from from a cron daemon built with "cd /usr/src/usr.sbin/cron && make CFLAGS=-g LDFLAGS=-static clean all" -- then run cron and "kill -6" it after it has started to exhibit this behavior. The bug's cause could be a stray pointer or an off-by-one error, but seeing what was in the data structures may help.
