Resource Consumption

I previously posted that GD was giving me grief after a while, once I had moved the development of my site over to a Windows machine running Apache. I believe I now know why there were problems. After a while, I began receiving error messages and they would output in the middle of the image code, causing the image to break. Setting error_reporting to 0 allowed them to load. Now I have another problem. It seems that after Apache uses a file, it does not release it. I was able to display a sample image using a TrueType font file, and I was able to see the text perfectly. After refreshing, the text portion of the image did not work, but other elements of the image did. I wrote $php_errormsg to a logfile and was able to see the following error: Could not read font However, I KNOW the font is there, and it has loaded it before. I double-checked to make sure, and it was still there. It seems that it cannot open the file or something - as if another process were using the file. The only explanation I can think of is that Apache never let go of the file after using it. Is this a possibility? Remember, I am using a Windows 2k platform. - Jonathan
