FireWall-1 FAQ: Too Many Open Files on Solaris
Please note: This content was from when I was operating my FireWall-1 FAQ site, which I stopped operating in August 2005. For some reason people still have links to this stuff on the Internet that people are still clicking on.
I am making this information available again AS IS. Given how old this information is, it is likely wildly inaccurate. I have no plans to update this information.
If you're still running versions of Check Point VPN-1/FireWall-1 where this information is still relevant to you, do yourself a favor and upgrade to a more recent release. If you happen to be running a current release and the information is useful, it's by happenstance :)
You need to increase the number of file descriptors available to your system. In Solaris, add these entries to /etc/system and reboot:
set rlim_fd_cur = 512
set rlim_fd_max = 1024
