It would make sense to leave it alone unless a config option was set with the desired number of max_fds, though. The fact is that RLIM_INFINITY does not work for RLIMIT_NOFILE in Linux. You have two upper limits: the hard limit, and the max number of open files per process (which can be raised at runtime), and setrlimit will EINVAL if you breach either limit. I am not sure if Solaris acts the same, but I would not be too surprised if the behaviour of the two kernels is similar. -- "One disk to rule them all, One disk to find them.
