    Centos 6.4
I am using Jenkins 1.517 on Linux Centos, and it is working without any issues.
However soon as I try to upgrade to any newer revision, most of my jobs disappear from the dashboard. 
I can still see some of the jobs there but not all of them. Once I revert the update back to 1.517 I can see again all my jobs.
I have 4 nodes on my setup, and couple of plugins installed:
- Rake plugin
- Rvm plugin
- Bulk builder
- Disk usage
- Rake plugin
- Periodic reincarnation plugin
- Green balls plugin
