So, here is my setup: a newly installed Windows Server 2012. The only software installed on it beyond the operating system is Apache 2.4.7 and PHP 2.4. The computer is in a LAN behind a router. The router tunnels port 80 to port 80 in this computer.
After I set up my website, everything was working perfectly: I could see the web pages from outside my LAN, PHP was executing, accesses were logged.
Then after a couple days, I could not open the pages from outside the LAN. From within the LAN, I could open them sometimes and sometimes they wouldn't.
Some facts:
- From within the server itself, I can open all pages.
- If I telnet to port 80 either from within the LAN or from outside, a few times the port would answer but wouldn't serve the GET request, while other times it just does not reply.
- Netstat shows port 80 binded to httpd.exe.
- If I make the router tunnel port 80 to another computer in the LAN, I can serve pages from this other computer, so it doesn't seem like the router is the problem.
- The server does not answer to vpn connect attempts either. It does open connections to Remote Desktop, however, even from outside the LAN (both ports tunnelled by the router).
- I have tried all this both with Windows Firewall activated and not activated. I have also checked the rules, and the only rule that mentions port 80 is the one for Apache, and is set to allow all.
- No error messages are reported in Apache logs.
- Restarting the server did not seem to make a difference.
I cannot make sense of all this. Any troubleshooting suggestion will be very welcome. |

Do you have in your config the following ?
AcceptFilter http none
AcceptFilter https none
EnableSendfile off
EnableMMAP off
Is advised with the kind of issue you have. |

Yes, I found that in some thread and I tried. Made no difference.
Something that I forgot to mention is these messages that appear in the error log (it is not obvious to me if they are actually reporting an error):
| Code: |
[Tue Feb 11 18:37:55.829173 2014] [core:notice] [pid 1256:tid 424] AH00094: Command line: 'C:\\Program Files\\Apache24\\bin\\httpd.exe -d C:/Program Files/Apache24'

The error.log data is generally consistent with normal start-up/shutdown messaging (e.g. there are no "errors" in what you posted -- these lines will attempt to be written to the error.log no matter what).
The only possibility of an error lies in the following line:
| Code: | [Tue Feb 11 18:37:56.533257 2014] [mpm_winnt:notice] [pid 3264:tid 300] AH00354: Child: Starting 64 worker threads.
[Tue Feb 11 18:37:57.319352 2014] [mpm_winnt:notice] [pid 2492:tid 308] AH00364: Child: All worker threads have exited. |
The line
| Code: | | [Tue Feb 11 18:37:57.319352 2014] [mpm_winnt:notice] [pid 2492:tid 308] AH00364: Child: All worker threads have exited. |
is usually printed during server shutdown. Given the timestamps in the log, it seems to indicate there might be a server immediately shutdown after start up.
Two potentially odd things in the error.log data you posted are:
A) there seems to be a missing "Parent: Received shutdown signal -- Shutting down the server." directive like in the following:
| Code: | [Tue Feb 11 00:47:14.449172 2014] [core:notice] [pid 1908:tid 376] AH00094: Command line: 'C:\\Programs\\Apache2.4\\bin\\httpd.exe -d C:/Programs/Apache2.4'
[Tue Feb 11 00:47:19.285181 2014] [mpm_winnt:notice] [pid 2764:tid 276] AH00354: Child: Starting 64 worker threads.
[Tue Feb 11 05:35:39.700155 2014] [mpm_winnt:notice] [pid 1908:tid 376] AH00422: Parent: Received shutdown signal -- Shutting down the server.
[Tue Feb 11 05:35:48.482657 2014] [mpm_winnt:notice] [pid 2764:tid 276] AH00364: Child: All worker threads have exited. |
B) the pid/tid for these lines don't match between them like so:
| Code: | [pid 2764:tid 276] AH00354: Child: Starting 64 worker threads.
[...]
[pid 2764:tid 276] AH00364: Child: All worker threads have exited. |
vs. your log
| Code: | [pid 3264:tid 300] AH00354: Child: Starting 64 worker threads.
[pid 2492:tid 308] AH00364: Child: All worker threads have exited. |
