Ubuntu 14.04 x86_64
OpenJDK-7u101
Jenkins 2.17
Multi-branch-project 0.5.1
8-core CPU | 8GB RAM |
JVM: -Xms2048m -Xmx 2048m
Right after doing branch-indexing to create 400 branch jobs,
Jenkins starts to response super slow when open any pages (job page, manage jenkins page, etc).
And after delete the Multi-branch job of 400 branch jobs,
everything is back to normal.
From the log,
I don't see any out of memory error.
But I do see the Java process has high %CPU (400~500) with about 1.9G RES memory.
