I have installed Condor 6.6.9-dynamic version on SuSE 9.2 Linux, kernel 2.6.8-24.13-default and got this error message. (see below). Setting MEMORY manually did resolve the problem with condor startup, but it would be nice to get it fixed at some point.

All versions of Condor from 6.7.2 and onward should have this bug fixed.
