This means that context 40000 had a process named pg_ctl that tried to
access /dev/pts/0, which belongs to another context (in this case, context
0). This is usually an indication of using vserver ... enter, so it is
safe to ignore, and it has already been blocked.

This means that a guest still had 29 pages of VM accounted to it when it
died. Typically, this would point towards some obscure accounting bug
somewhere in the kernel...
