I guess because 'suspended' is missing from the output of 'vzctl status' 
command for such CT the attempt to stop a CT in such state (running and 
suspended) has to be properly traced. For example, 'vzctl stop <CT_ID>' 
has to print something like "CT is running and suspended. Please, resume 
it by executing 'vzctl chkpnt <CTID> --resume' command in order to stop 
it". Right now the action 'vzctl stop <CTID>' on running and suspended 
CT ends with "Unable to stop container: operation timed out" what is 
expected.
