Server Unresponsive Issue


(John Savidge) #1

Hi,

Two mornings in a row now my Nethserver install has locked up for want of a better explanation forcing me to reset the VM it runs on.

When I try to access the console its unresponsive too. After a reboot it functions perfectly well.

Nothing to indicate cause in the messages log? Where else can I look to find the issue?

Thanks

John

Depending on your virtualization there may be logs too (ie. vmware.log). Do you use some virtualization backup tool?

Are there entries in /var/log/messages after the system freeze? Does it happen at a specific time? A cron job could be the trigger…

Nothing significant to my eyes.

VMware logs extracts:

There are no corresponding events or tasks in ESXi for the nethserver VM other than the open vm tools going offiline at about 7:15am.

Also, VMware backup not yet implemented. Risky!

The console is inaccessible or just slow?

It could be a kernel panic, but you should find something inside the logs.
From the pasted log, I can’t see anything strange.

I could see the login prompt but could not type anything.
