HTTP Server Crashes

[Umair]

Apache server currently hosts two sites, one internal site and the other being DekiWiki.
DekiWiki was configured to run on port 90 (as a virtual host).

Now, before the installation of DekiWiki, the server never went down.
Whereas after the installation,the server is crashing moreoften.

The log shows no special output just after and before the crash.
However i was able to dig out some error messages which were raised but did not cause the server to crash.

[Mon Aug 13 17:36:46 2007] [error] ap_proxy_connect_backend disabling worker for (localhost)

I was also trying to change the site-style of Deki, when i got the following error in the logs (thats when apache crashed):

[Tue Aug 14 10:36:31 2007] [notice] Parent: child process exited with status 3221225477 -- Restarting.

After this, the server is crashing more often without any special error message.

Any ideas`??

Now there seems to be some problem with the DekiWIki itself.
I am unable to naviagate to any other page except the main page.

The DekiWiki Log shows the following error:

Don't tell me that i am the only one who is facing this problem !!!

[royk]

is your config table in mysql empty? it seems to be missing the config_key = 'security/api-key'

[Umair]

um...yes, it was there..
It was working fine after the first install. Only when i did the restart, i got these messages.
anyhow i removed the installed files with a fresh copy.

Now, i am getting some interesting results :

This may sound wierd, but on every user click (request for DekiWiki), the HTTP server goes down.
It does however manually restars itself. But the site hangs on.
Now, this starnge behavior of HTTP server crashing down evolves only when the request is to a Deki site.

For the reference,
1). The OS is Windows Server 2003.
2). The HTTP server is Apache
3). The Virtual host of DekiWiki is configured to work on port 90.

Figured out...
Man it was so exhausting...!!

[Wed Aug 15 12:00:21 2007] [notice] Parent: child process exited with status 3221225477 -- Restarting.

This was the main issue!
I had been blaming DekiWiki untill now, but it seemed that there were larger forces involved

If you have a W32 OS and are running Apache with PHP 4.5+ then a common reason is that you installed as a module and are using the Zend Optimizer.

As tested we found that if your php.ini file is in your WINNT or WINDOWS directory and you leave the php DLLs in the c:\php folder then the problem will persist.

I tested by commenting out the bottom three lines in my php.ini file as follows;

[Zend]
#zend_extension_manager.optimizer_ts="C:\Program Files\Zend\Optimizer\lib\Optimizer-2.5.10"
#zend_extension_ts="C:\Program Files\Zend\Optimizer\lib\ZendExtensionManager.dll"
#zend_optimizer.optimization_level=15

It works like a beauty !

excellent! thanks for posting this - i'm sure more people will run into this problem

[Umair]

By the way,
I just bumped into my COnfig table data :


mysql> select * from config;
+-----------+-------------+--------------+
| config_id | config_key | config_value |
+-----------+-------------+--------------+
| 1 | ui/skin | mindtouch |
| 2 | ui/template | ace |
+-----------+-------------+--------------+
2 rows in set (0.00 sec)

Is this Normal ??

I am just reffering to your earlier post which stated :

is your config table in mysql empty? it seems to be missing the config_key = 'security/api-key'

as i have started having these errors out of a sudden again :

2007-08-20 10:31:26,073 [2748] DEBUG MindTouch.Dream.DreamMessage - Response: In
ternal Error(site deki has failed to initialize or did not start up properly: In
itialization exception: Value cannot be null.
Parameter name: An api-key is not configured for this service)

I really wonder what triggers the application to lose its consistent State !

went through an earlier post and got fixed

http://forums.opengarden.org/showthread.php?t=459

The Bug reported was :
http://bugs.opengarden.org/view.php?id=2392


First Question :

What should be the value for the field "storage/fs/path" in config table ?
I saved the value to be : C:/deki-hayes/web/attachments as was stated in the reported Bug Manual.
With attachments being a new folder created.
Problem:
There was however one problem due to these changes,The image uploading does not work at all.
No error, nothing.!
I upload the image, but it is not shown anywhere.


Second Question:

Why does this Bug :
http://bugs.opengarden.org/view.php?id=2392

occur so often?
I mean, why does the config table gets wiped off by itself ?

That should be valid value for "storare/fs/path". Can you make sure you have a "storage/type" with value "fs" ? Also, you'll need to restart dekihost after making direct changes in to the db config table as it's cached in memory. Check your bin/logs/warning.log for errors
