Mikko Peltonen reopened JENKINS-13154:
--------------------------------------


Jenkins 1.463 did not fix this problem for us. We're still seeing similar 
congestion, and many of our builds are stuck for tens of minutes in "Waiting 
for Jenkins to finish collecting data" at the end of the build.

I'll attach another thread dump taken with 1.463.

> We are seeing repeatable very heavy lock congestion with FingerPrint.save.
> Jenkins apparently slides down to a state where a lot of threads have locked 
> / are competing for a lock on FingerPrint instance and are competing for a 
> lock on AnnotationMapper (a singleton). Everything grings to a halt.
