Run "once"? For how long? How will it be disconnected? Truss can be rather intrusive for inspection. For every entry/exit to a system call, it forces the OS to stop the process, wait for truss to do its work, then restart the process. This can (and has) had detrimental effects on production systems. Now if your process doesn't do much, and the load on the application is low, you can increase the latency and probably no one will notice. But if you're already bogged down, then its likely to be very noticable. Dtrace is a much better option. It could be worth it to build a similar system on Solaris 10 even if production isn't there just to try to see what's happening.
