Hi Guys,
i need some help to check why my company ESXI 5.5 server which was built last dec 2013 suddenly shutdown by itself.
following is my finds from the events
At least one coredump target has been configured. Host core dumps will be saved.
info 7/3/2014 10:37:53 AM XXXXXESXI01.PXXXXXX.SG
I am able to extract the logs from the ESXI server from the vsphere client using the export system logs settings. i have upload the logs to my dropbox account
https://www.dropbox.com/sh/pmw6qq5bf9w02jl/AAAp8nNHfjIm6NquJN6sCS2Sa
From the vmksummary.log
2014-07-02T21:29:37Z bootstop: Host is powering off
2014-07-03T01:56:33Z bootstop: Host has booted
which told me it shutdown on 2014-07-02T21:37Z
on the ESXI 5.5 server log, i found the following. Seem like something trigger a shutdown. Any one can advise me what causes the shutdown?
