I have the same problem. However, my 'current' version is a bit old, so the daemons are a bit more stable. They do this 1-4 times per week. ftpd,sshd and inetd, exactly as your describe. Moreover, inetd has a more interesting behaviour sometimes: it can work good a day or longer then issue approx. 200 messages in 2 seconds about "exit on signal 11", then any logging activity disappears...
