Ok, I've swiped the sendmail5.61+ida1.2.8 from uxc.cso.uiuc.edu, and in the middle of compiling conf.c, it bombs with FSCALE and FSHIFT undefined.. I assume these are numbers to scale the values in avenrun[0] which must be the load average, but what the heck are the values supposed to be?? They're not defined in conf.h... Again, if too simple, replies to icsu6000@caesar.cs.montana.edu or utah-gr!mts-cs!icsu6000

It tries to be "friendly" by not spending cpu-cycles on mail delivery if the system is very busy. If your system is to be used primarily for mail (yes there are such systems) and other activities are considered less important this sendmail behaviour is not even desirable.

I ran into this on a Ultrix system myself. The problem is that avenrun[] is either a float or a long and the arithmetic operations to it in getla() differ significantly. The fix is to grep the type of avenrun in your /usr/include/*.h (or /usr/include/sys/*.h) files, then change the #ifdef in conf.c to use the correct type. Paul Pomes UIUC CSO
