It happened again this morning. (Funny it should be a Monday morning again.) The Zimbra VM would run for 7 minutes and then lock up with 100% CPU load. When I tried to look at the console of the VM, the problem became apparent. I got the warning message:
Code:
enconsole: Could not read tty from store: No such file or directory
This was solved very simply by running:
Code:
/usr/sbin/xenconsoled
on Dom0. It seems that it had taken 7 mins for the console buffer to fill up and nothing was emptying it, so the VM hung.
Now that I can see the console, it is full of the following error messages:
Code:
4gb seg fixup, process slapd
I will probably have to sort that out, but in the meantime at least I have a working Zimbra.
