Citrix Xen Server 5.6 – CDROMMON using 99.9% of CPU
Posted by Maz in Citrix Xen Server, Virtualization on January 18, 2011
Environment:
- Citrix Xen Server 5.6
- Dell 2950
Issue:
- The server is relatively fast at the start up. After few minutes it starts to slow down and then the VMs become virtually unusable.
- Using Console or SSH run TOP command and you observe that CDROMMON process is taking 99.9% of the CPU
Resolution/Workaround:
- Kill the CDROMMON process using:
Kill <pid></pid>
- Disable the CDROM in the BIOS of the physical machine
