Specs: Unix SCO 5.0.4
We are running Sco 5.0.7 server in a production environment.....Ive been here for 5 years and all of the sudden in the middle of the day ftp and telnet slow to a crawl. It still works but takes too long to login and some jobs are timing out. Doing a sar command the server seems to be running great. A reboot will fix every time. Any ideas?
