Hello, I'm working on some programs that require very large numbers of files open per process. 200-500 easily. I've done some research, and came to /usr/src/sys/conf/param.c... I notice that the system-wide-limit for open files is the same as the per-process-limit for open files. My main question is this: What, if any, ramifications will changing 'maxfiles' in param.c to increase max open files system-wide? If 'maxfilesperproc' is different from 'maxfiles' will that cause any problems? Additionally, Will I run into other problems with regard to high file descriptor numbers? I know that on Solaris (2.5 anyway) even though you can kick the max-open-files per process up to 2048, the FILE structure limits the file descriptor number to 1 byte, to 256 total. Will I run into similar problems with FreeBSD? Any Help would be appreciated, Jay --- Everyone can be taught to sculpt: Michelangelo would have had to be taught how not to. So it is with the great programmers.
