I am getting this error when going to the website. I checked the atlassian-bamboo.log for errors and see this entry near the bottom.
2019-09-30 16:58:53,464 FATAL [localhost-startStop-1] [DefaultBootstrapManager] Validation tests failed: [Task 51404 failed with exception: Failed to list contents of /var/atlassian/application/bamboo/caches/plugins/felix/felix-cache]
I updated permissions on that folder to the bamboo user, restarted bamboo and it did not fix the issue. I also stopped bamboo, removed the caches folder and restarted bamboo. That did not resolve the issue either.
I also tried upgrading to the latest version Atlassian Bamboo version 6.10.3 build 61008 and that did not help. I was on version 6.9.1.
What else should I try?
