I'm definitely no expert but... * What does it say when you 'ldd' the nagios binary? Are all the libraries the binary is linked against able to be found? Are those libraries up-to-date? * Where did you get nagios from? Did you compile it or is it pre-built? If pre-built, are there any updates? * I don't know Solaris well enough to know how to trace your running nagios with a very simple configuration, but that might be the next step. strace?
