I have Jenkins installed on Production and Non Prod servers and this has been running since Jan 2017 with out any issues. The last successful build was performed on September 03, 2018. I tried to build my projects last week and started to see an issue on all my project builds both in Production and Non-Prod environments.

The build version is visible and then it suddenly stops to show the build progress and also shuts down the Jenkins server. The build log shows build is successful and build.xml is missing from the recent builds. Once I start the Jenkins server(as it was stopped) and check the console for build history, the recent build history is not displayed.

I do not see any error particular to this problem in the logs.

This happens for all my projects on both the Servers and there has been no changes done by us on these servers. Please look into it.
