Ye old CogDogBlog seems to be teeter-tottering long; I am seeing a lot of 404s and Internal Server Error 500s, and the error logs are rife with unhelpful details like “premature end of script headers”. My last round of tweaks aimed at memory shortages has not helped, and it seems time for a round fo straw grabbing.
What i think I know is that PHP is running out of memory before it can finish executing a big request, hence the death by early script headers. The next step of sleeve rolling up involves putting the blog on the hoist and banging the wrench on a few pipes underneath.
I have a choice:
- Try to identify a RAM sucking plugin. This would mean activating the TPC! Memory Usage plugin. Like the old OS 9 days on the Mac of identifying a bad extension, I would have to disable one plugin at a time, reload a page, and see what effect the lack of a plugin has on the RAM needs. This seems as fun as dental surgery.
- Put the blame on the theme. It’s possible something in my theme is going wonky, and it just might be the jquery stuff that creates the blog top slideshow of flickr images. I could do a quick switch to the TwentyTen theme, and see the memory impact (the test might be quick). Re-doing a new theme might be fun…
If there is something else I ought to be poking around in, please let me know.
