[Xen-users] Xapi does not start

[Waqar Khan <waqar.khan@xxxxxxxxxxxx>]

Hi all,

 

I have a weird issue with xapi on xen 6.2.  Below is the errors in the /var/log/messages file when I run service xapi start

When doing xe-toolstack-restart I see a lot of OMMkill errors. Its killed everything from sshd to xcp-rrdd-iostat. The problem with this, however, is that its got loads of memory free. If I restart toolstack and check the memory usage it stays at arounf 3GB free memory. So why does it think its out of memory when free command shows 3GB free?

 

Thanks in advance.
