I am having an issue with my vCenter 5 essentials server. We've been running this server for approx 2 years, and about a month ago this problem popped up. Seemingly out of the blue the server crashes, however the issue is resolved with a reboot of the machine.
The following is information that would be worth while.
- When the server crashes you cannot login to it via vSphere and it stops sending alert e-mails
- When server crashes you can sometimes log into the console, but not always
- The server will respond to ping after it's crashed
- I've looked at the
/var/log/messagesright after a crash but nothing really jumped out at me (I may have missed something, I'm not a linux guru by any means)
- The crashes happen sporadically with no real rhyme or reason (that I can see) as to when they might happen.
I have also noticed some "Stateless" alarms have shown up as of late but I'm not sure if they're related. I've researched them but can't find a whole lot on them. An example is below.
Stateless event alarm
Alarm Definition: ([Event alarm expression: Status change])
vCenter Management Webservices status changed from green to yellow
I'm not sure if these are related. Does anyone know where I can look to try and figure out why these crashes are happening? Perhaps a log file I've missed.
