      Jenkins 1.570 (and many previous versions) stop responding to any HTTP requests after running for somewhere between 5 minutes and an hour. Increasing the heap size didn't seem to help, and jmap -heap seems to indicate that there is enough memory available.

      jstack -F (jstack failed without -F) seems to indicate that all the threads are blocked, but I can't tell why Jenkins doesn't respond to HTTP requests, or even if there is anything I can do to fix it other than restarting the entire Java VM.

          What JRE are you using? Are you able to use an Oracle JDK 1.7? If so, does the problem occur there as well?

          The problem does occur on Oracle JDK 1.7.

          When I opened this ticket, we were using Oracle JDK 1.6:

          Java version "1.6.0_26"
Java(TM) SE Runtime Environment (build 1.6.0_26-b03)
Java HotSpot(TM) Server VM (build 20.1-b02, mixed mode)

          Today, I upgraded our Jenkins box to Oracle JDK 1.7:

          java version "1.7.0_67"
Java(TM) SE Runtime Environment (build 1.7.0_67-b01)
Java HotSpot(TM) Server VM (build 24.65-b04, mixed mode)

          We start Jenkins using the jar runner. Here's the full command run:

          /opt/local/java/sun6/bin/amd64/java -Xmx4g -XX:PermSize=192m -XX:MaxPermSize=192m -jar /opt/jenkins/jenkins.war --httpListenAddress=127.0.0.1 --httpPort=8080

          Since I wasn't super specific before, the exact problem is that Jenkins continues to accept HTTP requests, but hangs without writing any bytes until the client times out. I've uploaded the output of the systemInfo page and new dumps from jmap -heap and jstack -F on JDK 1.7.

          Thanks!

          the server memory is full, it's normal that the server stops responding
