I have several users who have been using ^Z to stop & restart
emacs jobs - they are not the best housekeepers & this has
resulted in a system crash "panic: timeout table overflow"
This irritates me for two reasons -
1: I don't think it should be that easy to crash the system
(its embarrasing, too - like when our 11/60 rolled
over dead because somebody put a book down on a keyboard)
2: Educating an ever growing group of ever less knowledgeable
users about something like this is a good way to go pre-
maturely bald (or postmaturely in my case)
Enough fun - how can I increase the table size and is there a
way already devised for flushing the table periodically?
Please lets refrain from flaming about novices & emacs.

You do not want to flush the table. The things in it are important! The table size is determined by `ncallout'. This is a `configurable' parameter, appearing in /sys/YOUR_MACHINE/param.c. This file is normally copied from /sys/conf/param.c, which says int ncallout = 16 + NPROC; where NPROC is `#define'd to something depending on MAXUSERS, where MAXUSERS comes from your config file in /sys/conf/YOUR_MACHINE. If you are running out of timeout table entries, you probably have maxusers set too low too; but you can, if you wish, just raise ncallout, either by editing the private param.c, or (more quickly) with adb: % adb -w /vmunix ncallout?D _ncallout: _ncallout: 122 ncallout?W 0t250 _ncallout: _ncallout: 7a = fa $q % This would raise ncallout from (e.g.) 122 decimal to 250 decimal. -- In-Real-Life: Chris Torek, Univ of MD Comp Sci Dept (+1 301 454 1516) UUCP: seismo!umcp-cs!chris CSNet: chris@umcp-cs ARPA: chris@mimsy.umd.edu
