I do not wish to alarm you, but it may be a sign of intrusion. Particularly if your intruder spots you have various scan tools run by cron.
To be crude, most intruders will install a rootkit so if you have not already done so, run chkrootkit or my fav, rootkit hunter.
Also you can consider (but too late if you have not already installed) file integrity checkers and if you are always on the net, host based integrity checkers.
I am not an expert in any of these fields, but please check them out.
