sounds strange, I'd suggest to do the following:

 - check system log and dmesg for 'unusual' stuff
 - try recent mainline Linux-VServer without grsec
 - run such a command with strace -fF and wait
   until it fails (provide that trace then)

nope, that might put a guest on hold, and so delay
the execution for some time, but doesn't kill it

maybe updating that wouldn't hurt either ...
