Jenkins 2.176.2
ec2 1.44.1
Jenkins EC2 nodes are constantly crashing with 100% cpu usage:
java.util.concurrent.TimeoutException: Ping started at 1563548484233 hasn't completed by 1563548724233 at hudson.remoting.PingThread.ping(PingThread.java:134) at hudson.remoting.PingThread.run(PingThread.java:90)
I tried both using "native ssh" and via jenkins-ssh and both have the same issue. It looks like the remoting.jar is hung up:
JvmTop 0.8.0 alpha - 14:58:59, amd64, 4 cpus, Linux 4.9.0-9-a, load avg 7.89 http://code.google.com/p/jvmtop PID MAIN-CLASS HPCUR HPMAX NHCUR NHMAX CPU GC VM USERNAME #T DL 4093 m.jvmtop.JvmTop 21m 1698m 18m n/a 0.50% 0.00% O8U21 root 12 3973 remoting.jar [ERROR: Connection refused/access denied] 6406 remoting.jar [ERROR: Connection refused/access denied]
Not sure how to further debug this.
