Have seen this too, no idea where the bug is, had to reboot the system.
Yeah, we also had to reboot, because even SSH login did not work anymore. Only a still running remote shell did work, until something (e.g. ps) wanted to touch /proc/*/*. Since this is a productive environment, I'll try to reproduce next week.
