Jenkins Job fail

[jnehring]

Many Jenkins Job fail with this error message. Usually it works when I hit build again for some times but this is very annoying and leads to a lot of questions like "we is my update not deployed on freme-dev?"

As suggested in a Jenkins forum, I restarted Jenkins. It seems it works better now. I leave this issue open because I am not sure if it is really fixed now.

I upgraded Jenkins to the latest version and restarted. The problem seems to be gone.

The bug still occurs

I upgraded all the plugins also. Then I build 5 jobs and the error did not occur once. So I think it is fixed.
