Project: oVirt - virtualization made easy
Issue Type: Bug
Components: Hosting
Reporter: Evgheni Dereveanchin
Assignee: infra
Priority: High
Today I found the PHX engine portal in running very slow. Looking at the
system, engine.log is full of stack traces with "java.lang.OutOfMemoryError: GC
overhead limit exceeded" error.
Memory on the system:
{{# free -m}}
{{ total used free shared buff/cache
available}}
{{Mem: 7810 3752 475 165 3582
3576}}
{{Swap: 4095 1097 2998}}
Engine version:
{{# rpm -q ovirt-engine}}
{{ovirt-engine-4.1.6.2-1.el7.centos.noarch}}
Kernel/java version:
{{# uname -a}}
{{Linux engine-phx 3.10.0-693.2.2.el7.x86_64 #1 SMP Tue Sep 12 22:26:13 UTC
2017 x86_64 x86_64 x86_64 GNU/Linux}}
{{# which java}}
{{/bin/java}}
{{# ls -l /bin/java}}
{{lrwxrwxrwx. 1 root root 22 Oct 6 05:16 /bin/java -> /etc/alternatives/java}}
{{# ls -l /etc/alternatives/java}}
{{lrwxrwxrwx. 1 root root 73 Oct 6 05:16 /etc/alternatives/java ->
/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.144-0.b01.el7_4.x86_64/jre/bin/java}}
Will put the HA in maintenance, restart and upgrade the Engine
