==3756== TO CONTROL THIS PROCESS USING vgdb (which you probably

...command...
==3756==
==3756== TO DEBUG THIS PROCESS USING GDB: start GDB like this
==3756== /path/to/gdb /var/memtest
==3756== and then give GDB the following command
==3756== target remote | /var/valgrind/libexec/valgrind/../../bin/vgdb
--pid=3756
==3756== --pid is optional if only one valgrind process is running
