VMware vCenter 6 Web Console doesn’t load or very slow


Update (05 Sept 2017):

After changing the value to 512MB we continued to have this issues on and off, contacted VMware Support yet again and now they have advised to increase the MaxPermMB from 512 to 1024 (which is apparently the max value this can go to). We will continue to monitor to see if there is any improvement.

Environment

VMware vCenter 6.0.0 Build 4541948 (Update 2a) – could effect other vCenter versions also.

Issue:

After a period of a week or more the vCenter Web Console slows down dramatically to the point where the website doesn’t load anymore and the browser times out.

Looking into the /var/log/vmware/vsphere-client/logs/vsphere-client-virgo.log file you it displays the following Out Of Memory error:

Run: less vsphere-client-virgo.log

vmware_outofmemory

“[2017-03-15T13:59:07.853+13:00] [ERROR] ing.timer.TimerFactoryBean#0 o.s.scheduling.timer.MethodInvokingTimerTaskFactoryBean Invocation of method ‘update’ on target class [class com.vmware.vise.vim.cm.healthstatus. HealthStatusUpdater] failed java.lang.OutOfMemoryError: PermGen space”

Solution:

  1. (Workaround) Reboot the vCenter, according to VMware Support you should reboot it often to ensure the vCenter doesn’t run out of memory.
  2. (Permanent fix) Increase the memory size for vspherewebclientsvc in the service-layout.mfx file from 256 to 1024.
    1. Use WinSCP to connect to vCenter Server
    2. Browse to and edit: /etc/vmware/service-layout.mfx
    3. Find the line with the firstboot_name ngc_firstboot
    4. Under the column ‘MaxPermMB’ change the value from 256 to 1024
    5. Save service-layout.mfx file
    6. SSH to vCenter Server
    7. Run: /etc/init.d/service vsphere-client restart

    Could you let me know what your SR# was that lead to GSS stating that you should reboot your vCenter Server regularly? That is not acceptable.
