I've noticed that the build failure emails from Jenkins have URLs that are no longer valid on the build server (see below for example). The build number at the end (the "/10") is the invalid part. Does Jenkins remove failed builds from the build history when the build succeeds?
BUILD FAILURE Build URL: https://build.kde.org/job/kmymoney%20master%20latest-qt4/PLATFORM=Linux,compiler=gcc/10/ Project: PLATFORM=Linux,compiler=gcc Date of build: Thu, 21 Apr 2016 06:15:19 +0000 Build duration: 1 min 41 sec
