请各位大神帮忙,我读一个文件结果在标准出错给我打印了这句话,说打开的文件太多。可是那个文件也不多。我拿其他小的程序就能打开而且没有错误。请各位大神帮忙解释一下这是怎么回事。谢谢
linux下 c socket 编程 我的程序客户端和服务端建立连接后,就用这个socket下载一个文件,大约3M,每次到2.8M左右程序就不动了。客户端关掉,然后在连接, 服务端就会报错:too many open files ,我只打开了一个socket而已,加上第二次的也就两个。为什么会报:too many open files 这个错误呢。有的时候select(socket) 时还会报Segmentation fault 错误,程序退出。郁闷死!! 哪位大侠之前遇到过类似的问题,麻烦指教1,2

In the Linux world, people usually just mount their ISO images by typing as root : $ mkdir /mnt/isotmp $ mount isofile.iso /mnt/isotmp -o loop And once they're done, unmount the virtual disk : $ umount /mnt/isotmp This can be very annoying. 本文来自ChinaUnix博客,如果查看原文请点:http://blog.chinaunix.net/u/19782/showart_270200.html

大家好,我在OS/2上写了一个通讯程序,写日志的时候老是出现fopen时的错误,提示 too many open files,不能再打开文件,可是我所有打开的文件都关闭了,这时怎么回事呢?
我写了一个应用程序,维持着客户端可能千于个客户端,最近发现日志文件里面出现这样的错误,首先文件不能被open了,然后accept返回“Too many open files” 我用ulimit -a,看到open files是1024 那么事情就有两个可能,第一我打开了超过1024个文件没有close,但是我想我打开的文件数量应该没有那么多。 另外还有一种可能就是每个保持连接的客户端都算一个open 的file.这样,我就只能调整open files的数量对不对? 可是我用非r...

有时候在程序里面需要打开多个文件,进行分析,系统一般默认数量是1024,(用ulimit -a可以看到)对于正常使用是够了,但是对于程序来讲,就太少了。 修改办法: 重启就OK 修改2个文件。 1./etc/security/limits.conf vi /etc/security/limits.conf 加上: * soft nofile 8192 * hard nofile 20480 2./etc/pam.d/login session required /lib/security/pam_limits.so ulimit -a查看 下 OK 本文来自ChinaUnix博客,如...
