Concurrency issue on session file on harddisk

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

the company I work for has a problem with teir intranet based on php. All 
intranet pages are framesets, containing a menu on the left and the content 
part on the right. Both frames use the same session file stored in the 
session_save_path. Often the following error occures:

When opening a frameset page sometimes one of the frames in it is not loaded 
properly - one time you see only a blank page, sometimes more ore less 
uncompleted and sometimes there is a CGI error displayed. When you then 
refresh the frameset page, in most cases both frames are loaded correctly, 
and if not - just refresh again until the page is displayed correctly in 
both frames.

But not every workstation in the local net has this problem. I found out 
that only computers using MS Internet Explorer 7 never have this problems. 
When using an older version of IE (6.x or lower) or Opera for example you 
have the problems mentioned above.

I tried to figure out where the problem is and found the following error 
message in the php log file:

 [08-Feb-2008 05:46:37] PHP Warning:  Unknown(): 
open(D:\PHPtemp\sess_7bcee023be7946983ac8ab3d4cce361f, O_RDWR) failed: 
Permission denied (13) in Unknown on line 0

In most cases this error results from improper read/write permissions on the 
directory (or file). But in our case this is not the cause. Because this 
problem occurs randomly and is not always repeatable, I used a file monitor 
which logs every access to the sess_*.* files in this directory, including 
system access like cache writing etc. Now I compared the times in the file 
mon log with those in the error log file where the error occured and found 
the following rows in it:

 05:46:37.937  php.exe:4648  IRP_MJ_CREATE 
D:\PHPtemp\sess_7bcee023be7946983ac8ab3d4cce361f  SHARING VIOLATION

D:\PHPtemp\sess_7bcee023be7946983ac8ab3d4cce361f  SHARING VIOLATION 
Options:  Open    Access: 00100001

Since there is always only one browser on the net using a particular session 
file only the two frame scripts executed by php.exe could have caused this 
sharing violation. Now I examined the other records around this sharing 
violations for the specified time and got the following results assigned to 
their process made using Internet Explorer 6:

As you can see the frameset page is processed in one part while the two 
frame pages are processed interleaved. When using Internet Explorer 7 the 
access to the session file is first made for the first frame and then for 
the second frame. But all other browsers we tested have interleaved access 
to the session file for the two frames as you can see in the log above.

So my assumption is that IE 7 first requests the frameset file like all 
other browsers too. When this file is loaded IE 7 requests the first frame 
as first - and when loaded it requests the second frame afterwards. The 
other browsers seem to request the two frame pages "at the same time" 
causing interleaved access to the session file by two php.exe instances. 
This results in sharing violations in most cases and some of these cases 
result in displaying uncomplete pages because reading the session data was 
not possible. So the php script which depends on the session data exits with 
the permission error message in the php log file.

So far my assumption. Is there an issue in php with concurrency access or is 
the operating system the producer of it? I don't know if this is the real 
problem, so I want to ask you for your opinion on my representation.

Alltogether we need a solution to solve this problem because this problem 
occurs more than we can accept and disturbs the work on the system. We tried 
to delay the loading process of the second frame but failed because most 
workstations have javascript disabled due to security regulations I have to 
follow. We also can't rewrite all php scripts since there are thousends of 
them in the intranet. For future projects we will use a database for it bat 
we need a solution for the old system.

Is it possible to make php trying again to read the session file for a 
second try when access failed due to sharing violation on the first try? Or 
perhaps a possibility to realise a delayed loading of the second frame 
without javascript and all this stuff? Since we use a lot of user defined 
funcions we were not able to migrate to PHP 5 yet. Will PHP 5 produce the 
same issue?

Our Intranet is running on an Intel Q6600 Platform with 4GB Ram, Windows 
Server 2003 64bit Standard Edition, IIS 6, mySQL 5.0.51a and PHP 4.4.7.

Please help us, you are our last hope *snore* ;)
