Yes, nrpe works just fine.

I attached a patch. Copy it to the affected Sol11 machines and do

 # patch -p0 < /path/to/patchfile

Essentially, the patch adds

 unalias -a

to the top of /etc/opt/csw/init.d/cswnrpe.

The problem is, that in Sol11, /bin/sh is a link to ksh which by default
defines some aliases, and `stop' is one of them. The nrpe start script dies on
line 58, because a function is defined which is also called `stop'. So, when
the script is read, line 58 is expanded to 'kill -s STOP' which doesn't make
much sense in that context.

Let me know of the outcome.
