I've tracked this down to this entry [BST Jul 21 14:39:44] info : restart service 'openvpn_server' on user request [BST Jul 21 14:39:44] info : monit daemon at 3426 awakened [BST Jul 21 14:39:44] info : Awakened by User defined signal 1 [BST Jul 21 14:39:44] debug : monit: Cannot open proc file /proc/23953/stat -- No such file or directory [BST Jul 21 14:39:44] debug : system statistic error -- cannot read /proc/23953/stat
I assume monit was trying to check the status of process 23953, but why would it fail?
