Lighttpd

Installed lighttpd 1.4.37 on Debian 8 with armel packages:

lighttpd, php5-fpm, php5 and php5-mysqlnd

System info:

# uname -a
Linux localhost 2.6.32.9-default #3 Thu Dec 29 20:07:17 HKT 2011 armv5tejl GNU/Linux

Using Chrome Browser, connect the MariaDB installed on Windows 7.

All other PHP scripts running OK. But whenever I made the connection by "mysqli", it will generate the error below.

2015-10-22 17:03:24: (mod_fastcgi.c.2391) unexpected end-of-file (perhaps the fastcgi process died): pid: 0 socket: unix:/var/run/php5-fpm.sock

Tried the exact same configuration and installation on a Debian x86 machine. Everything works fine.

Don't know what happened.

Here is my /etc/lighttpd/lighttpd.conf file:

I tried to look into the source code at mod_fastcgi.c line 2391

Find that the error message generated because the toread was equal or less than 0.

When i tried to debug the toread, by the following code, before the if statement as below

        if (ioctl(hctx->fd, FIONREAD, &toread)) {
                if (errno == EAGAIN) return 0;
                log_error_write(srv, __FILE__, __LINE__, "sd",
                                "unexpected end-of-file (perhaps the fastcgi process died):",
                                fcgi_fd);
                return -1;
        }
//---------------------------------------------

        FILE* file;

        file = fopen("/var/log/lighttpd/debug.txt", "wt+");

        fprintf(file, "%s %d", "ss", toread);

//---------------------------------------------

        if (toread > 0) {
                char *mem;
                size_t mem_len;

                     .......

After recompiled the code, it won't write anything to the debug.txt file. the debug.txt was generated OK.

I was really confused, and had no clue why toread value won't output to the file.

Any help, are appreciated.

Thanks
