Recently we tried to migrate some applications form SunOS 4.1.3 to Solaris 2.4.
Major of these applications are using network TCP/IP communication. (We didn't
change the codes to TLI, since we have so many of them) One big concern we found
that the memory usage for Solaris 2.4 is almost 4 times more than it was running
on SunOS 4.1.3. We are worry about this kind of memory consumtion, since our
production machine are mostly SLCs and ELCs.
I don't know if anyone had this problem before or it is wrong of the way we are
measuring the memory usage. There are two places we are check: the swap space
and the result from "ps" command.
