I am not sure which is the right mailing list, so sorry about the cross-posting:
I want to use a lot of memory in my program, so I set the following in /boot/loader.conf: kern.maxdsiz=2147483648 kern.maxssiz=2147483648 kern.dfldsiz=2147483648 Then I run this simple program: #include <sys/types.h> #include <sys/time.h> #include <sys/resource.h> #include <stdio.h> int main() { struct rlimit rlp; getrlimit(RLIMIT_STACK,&rlp); fprintf(stderr,"%lld %lld\n",rlp.rlim_cur,rlp.rlim_max); rlp.rlim_cur = 512*1024*1024; fprintf(stderr,"%lld %lld\n",rlp.rlim_cur,rlp.rlim_max); setrlimit(RLIMIT_STACK,&rlp); exit(0); } and it crashes like this: 2147483648 2147483648 536870912 2147483648 Bus error (core dumped) Maybe I am expecting too much from the system. I have a dual Athlon MP system with about 3G of RAM, and I want to be able to use a good portion of this RAM in a single process. But I also want to use linuxthreads so that I can take advantage of the two processors. But linuxthreads uses setrlimit, and crashes in a similar way to my simple program. I looked at the kernel code in /usr/src/sys/kern/kern_resource.c at the function dosetrlimit, which I guess is where the action takes place, but I have no idea what to make of it. -- Stephen Montgomery-Smith [EMAIL PROTECTED] http://www.math.missouri.edu/~stephen To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message
