The easiest thing I would suggest is to run a quick 2H 1D and see what it
looks like. The Tol lock is expecting 4 peaks. If the shim is way off, maybe
it's having a hard time getting started?

> Subject: [AMMRL] lock error on Bruker AVANCE III HD
HI All,
I have a weird lock problem on my 600 MHz Bruker AVANCE IIIHD system.
It won’t lock d8-toluene (the same sample locks fine on my 500 AVANCE III
system).
I get an error.
“Not all additional peaks could be found”.
It will lock D2O, CDCl3, d6-benzene, and even d8-toluene if I tell it it is
benzene. A screenshot of the error is below.
Thanks for your help.
