Ok, I just got a new Novell server to test on. Simplest case that will
leave an open file:
int main(int argc, char** argv)
{
int fd;
char buf;
if(argc != 2) exit(1);
fork();
fd = open(argv[1], O_RDONLY);
if(fd == -1){
printf("can't open\n");
exit(1);
}
sleep(1); /* probably just needed to "sync" the two processes (?)*/
read(fd, &buf, 1);
sleep(1);
close(fd);
}
This will not always leave an open file, but often enough that I'm
very suspicous that there is some race condition.
This doesn't crash the novell server though, but repeat this 200
times, and it will happen.
Doing `(while /bin/true; do cat foo.txt > /dev/null; done) &' three
times will leave approximately one file open per second.
Any ideas?
