Re: [9fans] crashing 9vx

[Philippe Anel]

Could not crash with your program, but it crashed quite fast with this one:

#include <u.h>
#include <libc.h>
#include <thread.h>

enum {
   NPROC=10,
};

void
crproc(void * p)
{
   int i = (int)p;

   while (1) {   
       int fd;
       char *name = smprint("/tmp/%d", i);
       fd = create(name, OWRITE, 0666);
       if (fd < 0) exits(nil);
       // free(name);
       close(fd);
       i += NPROC;
   }
}

void
threadmain(int, char**)
{
   for (int n = 0; n < NPROC-1; n++)
       proccreate(crproc, (void *)n, 4096);
   crproc((void *) (NPROC-1));
}
