I'm starting to work more with Freeswitch, and as such, I'm looking to implement it in a virtualized environment. My initial installation was onto a CentOS 6 OpenVZ container. However, the logs are showing this (many times):<br>

However, OpenVZ makes use of a shared kernel which in my prior experience, does not have the issues associated with fully virtualized technologies like VMWare, KVM, Xen, Hyper-V, etc. Am I incorrect or is this issue specific to Freeswitch (but apparently not so in use with Asterisk) ?<br>
