I'm wondering if this is hardware failure at this point, but don't know what to check. Many thanks for any help (even a 'give it up' ;) -Thor Clark thor@tabula.com PS (problem description) problem: After a few hours of activity, system will not start new processes of any kind. It will respond to pings, but that's about all - no telnet, login, http, etc. Background and interactive processes continue to run, but killing off interactive processes does not have any effect on the system - the only recourse is to physically reboot. This is now happening every ~3 hours. No kernel panic occurs, and no kernel messages are ever logged. The system has never recovered on its own ( down once for > 12 hours). system: 2.1 Release (from cd) - kernel recompiled, installed with maxusers 128 options "NMBCLUSTERS=2048" options "OPEN_MAX=256" options "CHILD_MAX=256" 16M, IDE, ASUS P55TP4, 3C509 ethernet runs CERN3.0 httpd, sends out a lot of mail, a few minor background processes, and a lot of short-term, cpu intensive scripts
