Amazon EC2 Force umount Volume does not work - linux

I am trying to detach an Amazon EC2 Volume, but It get stuck some where, here is the strace output, I tried fuser -km /mnt/web but none of the option is working.
I also tried ls /mnt/, and deleted the entry from /etc/fstab but it still won't work.
Strace Output
user#server:~$ sudo strace umount -l /mnt/web

Is getaddrinfo() a system call?

I was reading http://beej.us/guide/bgnet/output/html/singlepage/bgnet.html#syscalls when I found that getaddrinfo() is listed under the System Calls or Bust chapter.
I wanted to check if it really is a system call on my Debian 8 Linux system. But I can't find any evidence of it being a system call.
For example, I wrote a program foo.c.
#include <stdio.h>
#include <sys/types.h>
#include <sys/socket.h>
#include <netdb.h>
int main()
{
struct addrinfo *ai;
int ret;
ret = getaddrinfo("localhost", "http", NULL, &ai);
printf("ret: %d\n", ret);
return 0;
}
When I compile and run this program with strace, I don't see any call to getaddrinfo().
$ gcc foo.c && strace ./a.out
execve("./a.out", ["./a.out"], [/* 40 vars */]) = 0

I don't see getaddrinfo() mentioned in man syscalls.
$ man syscalls | grep getaddrinfo
$
So can I conclude that getaddrinfo() is not a system call on my Debian Linux system?
Is there a better way to definitevely determine if a given function is a system call or not on a given Unix or Linux system?

No, it is not. Your investigation proves it.
Additionally, you can try to find it in the Linux syscalls table. Or open man page for it check which chapter it is: 2 - system calls; 3 - c functions.

It is not a system call. It comes from the C standard library (libc).

git push fails on mounted davfs

I am trying to mount a disc with a GIT repo using davfs2 on Ubuntu 15.10. If I mount the disc using SSH or NFS (in the same target dir), I have no problem. When using davfs2, there is apparently no problem with regular file access / creation / edit, but when I try to do git push, I get this error message:
Counting objects: 4, done.
Delta compression using up to 4 threads.
Compressing objects: 100% (4/4), done.
Writing objects: 100% (4/4), 367 bytes | 0 bytes/s, done.
Total 4 (delta 3), reused 0 (delta 0)
remote: error: unable to create temporary file: Invalid argument
remote: fatal: failed to write object
error: unpack failed: unpack-objects abnormal exit
To /media/nas/all/repos/setup.git
! [remote rejected] master -> master (unpacker error)
error: failed to push some refs to '/media/nas/all/repos/setup.git'
I have tried setting use_locks to both 0 and 1 in davfs2.conf. It does not change the result.
Running 'strace git push' gives the following result. Please help me understand what I can do in order to make this work. git push seems to fail after some wait statements, as can be seen in the output. What can I do about this?

lighttpd cannot be started on centos 7

on centos 7 system, when i tried to start the lighttpd it show: [OK] . However when i check it with service lighttpd status, it show following log:

anyone has any idea with this kind of problem? i tried to change the port from 81 to 8080 and 8081 nothing worked.

Cgroup mount failed using cgconfigparser when configuring jstorm with cgroups

I am trying load /etc/cgconfig.conf using cgconfigparser to configure cgroup properties of jstorm.
My OS is ubuntu 14.04, username is 'whaty' and I have installed libcgroup1, cgroup-bin, cgroup-lite. There is no cgconfig.conf in /etc. so I create it manually.
Here is my cgconfig.conf
mount {
cpu = /sys/fs/cgroup/cpu;
cpuset = /sys/fs/cgroup/cpuset;
}
group jstorm {
perm {
task {
uid = 1000;
gid = 1000;
}
admin {
uid = 1000;
gid = 1000;
}
}
cpuset {
cpuset.cpus = 0;
cpuset.mems = 0;
}
}
I try to load this config using:
sudo cgconfigparser -l /etc/cgconfig.conf
The result shows:
cgconfigparser; error loading /etc/cgconfig.conf: Cgroup mounting failed
Here is my /proc/cgroups:
#subsys_name hierarchy num_cgroups enabled
cpuset 12 5 1
cpu 3 5 1
cpuacct 0 1 1
memory 0 1 1
devices 0 1 1
freezer 0 1 1
blkio 0 1 1
perf_event 0 1 1
hugetlb 0 1 1
Here is my mount of cgroup:
whaty#whaty:/sys/fs/cgroup$ ls
blkio cpu cpuacct cpuset devices freezer hugetlb memory perf_event systemd
Here is the strace of cgconfigparsser:

getconf returns 32 bit on x86_64 architecture

In one of my system, I observed below output.
root#base0-0-0-1-0-11-1:/root> uname -a
Linux base0-0-0-1-0-11-1 2.6.34.12-kairos-ksc-dec02-1800 #2 SMP Mon Dec 2 17:48:50 IST 2013 x86_64 x86_64 x86_64 GNU/Linux
root#base0-0-0-1-0-11-1:/root> getconf LONG_BIT
32
root#base0-0-0-1-0-11-1:/root>
The output from uname says the system is 64 bit while getconf says its 32 bit. Is there any reason for this mismatch?
I confirmed in my other systems where no such mismatch was found.
Please suggest. Thanks.

You can confirm which files getconf is picking up by running it through strace.
$ strace getconf LONG_BIT
Example
From my 64-bit Fedora 19 installation.
$ strace getconf LONG_BIT
