It starts with error Header already send

[jordi-oscommerce]

My config is:

Windows 2003

IIS 6

PHP 4.4.4

 

Sometime I get the following error in the phperrorlog

 

"PHP Warning: Cannot modify header information - headers already sent in .."

"PHP Warning: main(H) [<a href='function.main'>function.main</a>]: failed to open stream: No such file or directory in .."

"PHP Fatal error: main() [<a href='function.require'>function.require</a>]: Failed opening required 'H ...."

"PHP Fatal error: Nesting level too deep - recursive dependency? in Unknown on line 0"

"PHP Notice: Constant PAGE_PARSE_START_TIME already defined in .."

 

This is very strange because the site it almost the whole day online but sometimes I get these errors and then the

site is offline. And when I take look in the files where the error appear I see nothing strange also no

white spaces before the <?php tag or after the ?> tag.

 

It always start with "Cannot modify header information .." and then I get the rest of the errors and it is always in another

file.

 

And when these errors appear and I recycle the application pool of that site, the site is online again. And the errors

disappear.

 

Can someone help me??
