@Martin: Would be helpful for my case, especially that I don't have to use
an extra program (Rumpctrl)
I tried to change the number of available # of File Descriptors with sysctl
without any luck.
It seems that i have to adjust them with ulimit (which has to be pulled
from the NetBSD sources) or
is there another workaround ?
rumpctrl (tcp://10.0.0.2:12345/)$ sysctl -w
proc.2.rlimit.descriptors.soft=512
proc.2.rlimit.descriptors.soft: 128 -> 512
Tested against the program at the end of the mail. Seems to work fine.
Might be easier if rumpctrl had ps, but the first program really
always is 2, next one is 3, ... I can't actually remember if there's
some trick to list the processes without ps (except gdb). I'm almost
sure I knew how to do it 5 years ago, but apparently time heals all
synapses. Or at least I remember having to fix a bunch of stuff for
sockstat to get the command lines to display right ....
#include <sys/times.h>
#include <sys/resource.h>
#include <err.h>
#include <stdio.h>
int
main()
{
struct rlimit rl;
for (;;) {
if (getrlimit(RLIMIT_NOFILE, &rl) == -1)
err(1, "getrlimit");
printf("%lld %lld\n",
(long long)rl.rlim_cur, (long long)rl.rlim_max);
sleep(1);
}
return 0;
}
