Your Jenkins instance hangs when saving changes made in Mangage Jenkins->Configure System.


CloudBees Jenkins Enterprise

Agent Setup plugin


Enabling deploy on save now in the Agent Setups section in Manage Jenkins->Confifure System causes the hang to occur.

If you need this feature of the Agent Setup plugin the hang will occur, but it does eventually complete.
Generating a Support Bundle while the hang is occurring and reviewing the thread-dump.txt file in the nodes/master directory will show a thread with stack trace similar to:
