[Chameleon] Session lock, PHP Warning

[Gail Millin]

Hi List,

I am getting no image appearing in the viewer the rest of 
the page loads fine including the projection definitions. 

I am getting the following warning when running the sample 
viewer for chameleon in the PHP logfile: - 


[13-Jun-2005 12:26:18] PHP Warning:  fopen
(c:/Inetpub/wwwroot/tmp/sess_42ad6c72c00b1/lock): failed to 
open stream: No such file or directory in 
C:\Inetpub\wwwroot\chameleon\htdocs\common\session\session.p
hp on line 135
[13-Jun-2005 12:26:18] PHP Warning:  fread(): Length 
parameter must be greater than 0. in 
C:\Inetpub\wwwroot\chameleon\htdocs\common\session\session.p
hp on line 213

Also my session logfile tells me drawmap is pausing before 
opening (see below) : -

Why would this be happening? No image is coming up at the 
moment I think it might have to do with the creation of the 
lock file???? Has anyone else had this problem?

I am using Windows Server 2003, IIS6, Chameleon 2.0, and 
PHP 4.3.11

Any help or suggestions I would really appreciate

Thanks

Gail
