cron orphans

[Steven Stern]

I noticed the following in my logwatch email today:

 --------------------- Cron Begin ------------------------ 

**Unmatched Entries**
ORPHAN (no passwd entry) 
ORPHAN (no passwd entry) 


When I look at /var/log/cron, it seems that this error is generated whenever I
update my crontab via crontab -e

/var/log/cron:

May 12 08:35:19 ciscy crontab[26674]: (sdstern) LIST (sdstern) 
May 12 08:35:37 ciscy crontab[26675]: (sdstern) BEGIN EDIT (sdstern) 
May 12 08:36:00 ciscy crond[2326]: (tmp.15574) ORPHAN (no passwd entry) 
May 12 08:36:00 ciscy crond[2326]: (tmp.24677) ORPHAN (no passwd entry) 
May 12 08:36:00 ciscy crond[2326]: (tmp.26673) ORPHAN (no passwd entry) 
May 12 08:36:05 ciscy crontab[26675]: (sdstern) REPLACE (sdstern) 
May 12 08:36:05 ciscy crontab[26675]: (sdstern) END EDIT (sdstern) 

My question:  Is this really an error and indicative of a problem?
