在HP UNIX上申请内存的时候,一个进程超过785M就不能创建线程,怎么解决呢

void * child(void *args)
{
        printf("child thread start\n";
        int tid = pthread_self();
        printf("thread %d enter\n", tid);
        printf("child thread end\n";
}

int main(void)
{
        printf("main thread start\n";
        for(;
        {
        pthread_t pt;
        int ret = pthread_create(&pt, NULL, child, NULL );
        printf("main thread create thread the ret =%d\n",ret);
        sleep(1);
        char *p1 = (char *)malloc( 5 * 1024 * 1024 );
        if( p1 != NULL )
        memset( p1,'1', 5 * 1024 * 1024 );
//      free( p1 );
        }
   printf("main thread exit\n";
   return 0;   
}
结果
thread 156 enter
child thread end
main thread create thread the ret =0
child thread start
thread 157 enter
child thread end
main thread create thread the ret =11
main thread create thread the ret =11
main thread create thread the ret =11

这个貌似和你在HP-UX上还是别的unix上无关
你用 pthread_create 创建了 joinable 的线程，却不用 pthread_join 回收线程资源，到达线程数量上限了而不是内存上限

man pthread_create
man pthread_join
man pthread_attr

HP-UX 上你要看一下
1 kernel 参数 (kctune): maxdsiz, max_thread_proc
2 swapinfo
3 ulimit
