"Build execution is suspended due to the following reason(s):
Your total DEV@Cloud disk usage is over your subscription’s quota. Your subscription ‘foss-free’ allows 10 GB, but you are using 10257 MB across all services (Forge and Jenkins). To fix this, you can either upgrade your subscription or delete some data in your Forge repositories, Jenkins workspaces or build artifacts."
Solved.
@Kai: could it be that the problem is back?
Yes, but I already cleaned some space - it just takes a while for Cloudbees to notice that. Should hopefully be working again tonight.
Thanks!
Although I now see that the last build has failed because of the quota issue:
bumping this thread cause it seems that Mr. Jenkins is full again

bumping again… Mr. Jenkins is misbehaving again… 
edit: forget it, Kai fixed the space on the old Jenkins and informed me that PRs are still using the old one (to be migrated to the new later on)
oh wait… this (https://openhab.ci.cloudbees.com/) is the old Jenkins
the new is at https://ci.openhab.org/ and this one doesn’t have a problem… BUT…
in github for my PR #5709, I get the following message:
" Some checks haven’t completed yet. 1 pending check. Pending — Jenkins is validating pull request …"
and the Details link is pointing to the old Jenkings: https://openhab.ci.cloudbees.com/job/PR-openHAB1-Addons/
is the github repo https://github.com/openhab/openhab1-addons (and maybe others?) pointing to (and depends upon) the old Jenkins? (which is full)
