Hi, Here I have a MUD game running on FreeBSD, when there are more than 59 
users connected in, it will get an error message with appending to a log
file. The source code is as followings:
 
if (( fopen(fname,"a") == NULL){
  fprintf(stderr,"Error opening logfile\n")
}

Is there a maximum file descriptors limited? If so, how can I change it?

My OS is FreeBSD2.1 and the memory is 16M.

Best regaurds!
