A possible cause might be the /tmp file system not allowing files mapped in shared memory. If you do not need vgdb (i.e. not using vgdb directly and/or the valgrind gdbserver and/or callgrind_control and similar), you can probably bypass the problem by giving --vgdb=no. Would be worth in any case to investigate what is wrong with the very relevant suggestions given by John.
