| |
Please CC any replies to me at <ejones@uwaterloo.ca>.
I hope this has not been discussed before. I think I have searched the archive fairly exhaustively. This issue may also no longer exist on the 2.4 kernel series because I have not tested it on that kernel.
I have been experimenting with a web server (thttpd) which uses a cache of mmaped files to serve requests. It opens a file, mmaps it then closes it to avoid running into the perprocess file descriptor limits. Instead, it ends up running into the system file descriptor limits which makes the system unusable for anything but the web server process. FreeBSD does it differenly. Files can be mmaped and do not count towards the limit.
Does this issue still exist in the 2.4 kernel series? If not, are there any plans for resolving it? Any suggestions for how I could modify the web server to avoid making the system unusable?
Thank you
Evan Jones <ejones@uwaterloo.ca>
