I recently fired up an old mining rig after I found an old TrueCrypt file that I wanted to gain access to. I'm pretty confident my password is around 15 digits and even bruteforcing that with 7 GPUs isn't realistic as far as I can tell.
I've been playing with settings for the past several days and I've come down to:
I'm also guessing on the encryption I used so I may need to run this multiple times with different "- m" values
The problem with this is it only utilizes 1 GPU and instead of taking an hour or two to process thru the 8 or 9 so remaining characters I think I need it is going to take weeks or months. My dictionary file only has about ~10 or so phrases/words I probably would have used to begin the password, the remaining 8 digits could be anything.
I've read a bunch about the --stdout however when I add it to my code it appears to be starting up then I get a crash and another generic message about failure to allocate swap storage I cannot find anything helpful about.
If anyone has any ideas I would appreciate it, if any more info is needed please also let me know.

ATTENTION! Read timeout in stdin mode. The password candidates input is too slow:
* Are you sure that you are using the correct attack mode (--attack-mode or -a)?
* Are you sure that you want to use input from standard input (stdin)?
* If so, are you sure that the input from stdin (the pipe) is working correctly and is fast enough?
