when i googled i found this os-thread-startup hope it will help.
This is the comment i found some where on the net..

This is a useful link. It's good to know that some network problems block the OS thread startup and the wait event is literally expressed as "os-thread-startup".

I believe that the network problem is the main reason of login hangs - maybe 90% of them!

In that case, truss and it's families(strace, ...) might be the only reliable tools as the original post shows.
