It is possible that two patches on gerrit pass on their own, but when merged the combination of them causes a fault. That is due to the "rebase-if-necessary" policy we're using on gerrit, not enforcing another build verification when the master has moved on. In that case we can look at the master branch verification build on jenkins.osmosom.org (the one without "gerrit" in its name). The first failure in our master verification job is https://jenkins.osmocom.org/jenkins/job/osmo-pcu/1007/ suggesting that the causing commit was commit b3df58660f6e965799b18b5b87892a3272c4ccf1 Author: Max <msuraev at sysmocom.de> Log socket path on connection which doesn't make sense to me, because that is a log message tweak.
