Although you can increase the file descriptor limit for a 32-bit process (in /etc/system and using ulimit) and then successfully open more than 256 files, this is not safe and will often result in stack or heap corruption depending on what parts of stdio you use. In general the 32-bit stdio routines do not support file descriptors > 255. With the release of Solaris 10 8/07 (often referred to as update 4), there is a new interface to extend the FILE facility. Programming details are in the man page enable_extended_FILE_stdio(3C), and if you don't want to make any code changes, extendedFILE(5) describes how to do this for existing applications and binaries. Binaries compiled as 64-bit do not have this constraint and can open up to 65536 files without problems. HTH.
