Hello, I found what I think is a serious shortcoming in FreeBSD that needs to be addressed. I am running FreeBSD 4.4-RELEASE #0: Tue Sep 18 11:57:08 PDT 2001 I executed 'tar cvf tarfile.tar ~/' while I was at my ~/ directory. The tar file was being produced when the ttyv0 was being filled with messages. Here is an example: Feb 5 17:43:56 pc047113 /kernal: microuptime() went backwards (1550895.778303 -> 1550895.-694593171) Feb 5 17:43:56 pc047113 /kernal: microuptime() went backwards (1550895.839382 -> 1550895.832517) Feb 5 17:43:56 pc047113 /kernal: microuptime() went backwards (1550895.291637 -> 1550895.274690) This made my /var/log/messages extremely huge very quickly. My /var/log/messages was growing at a rate of approximately 70,000 lines per minute. Killing the shell from another terminal didn't work since the process kept coming back with a new PID. Had to 'reboot' in order to recover If any of my users pull this off when I am not around, this could be a lot worse. Something needs to be done to fix this.
