Hello list, Per Scott's request, I am posting this message regarding the server I had problems with few days ago. After disabling (ftpd) completely from (inetd), and after removing (-O2 -pipe) from the "make world" compilation, I am happy to announce that the server is working smoothly for the last 4 days, with no reboot at all. To remind the list, that server rebooted every 1-2 hours few days ago, for no aparent reason, and the only time I was next to it to see what's going on, I saw that the kernel panic'ed in (ftpd) process. To sum it up all, the server is working wonderfully now after disabling (ftpd) and removing (-O2 -pipe) from "make world" extra parameters.
