ulimit

How should one remove all potential artificial resource limitations for a process?

I just saw a case where a server application consumed resources so that some limitation was hit. The other shells into the same server etc were all extremely slow (waiting for something to free up for them; ie. prstat starting 5 minutes). It wasn't CPU/memory related problem so I think it has got something to do with ulimits / projects.

Already managed to set the maximum open files to 500 000 and it helped a little bit. However there is something else and I can not figure out what resource is maxed out. I can get some in-house administrator probably to check this but I would like to understand how I could make sure there shouldn't be any limitations!

If you think I am going the wrong way (would be better to figure out what limitation should be specfically tuned etc) please feel free to point me to the correct way. I know technical stuff - it's just Solaris 10 that is giving me headache :/
