"Can't open page" "Server busy" or "Dropped connection" error
Please forgive me if this is covered somewhere in the FAQs or if it’s mentioned in another thread. I searched, and I couldn’t find anything.
Sometimes when I mistype a <txp: tag, or use a malformed <txp:if_ statement, the page will completely fail to load, and Safari will return this error*:
Safari can’t open the page “http://example.dev/link…” because the server unexpectedly dropped the connection, which sometimes occurs when the server is busy. You might be able to open the page later.
Often, I can find the error by going through the txp logic in each page and form involved, but sometimes this takes a while. With no debugging comments to follow when I get this error, it can be hard to track down the error.
What’s the best way to troubleshoot this problem?
Thanks, all!
- Firefox, on the other hand, dislays a blank page with no source code, and Lynx says “Unexpected network read error; connection aborted. Unable to access document.”

Re: "Can't open page" "Server busy" or "Dropped connection" error
As I’m testing pages on FF I don’t know the Safari error you get. Here are — forgive me ;) — two FAQ pages regarding template problems. Hope they can help.

Thanks, Uli!
I tested it in Firefox too, but it doesn’t display anything. When I select View > Page Source, Firefox doesn’t show any source code either.
Thanks for the FAQ links— they affirm that I’ve been following the right steps. I’m already running Textpattern in debugging mode, which has been helpful in many cases; but in this case, when nothing loads, I can’t trace the txp logic in the debugging comments.
At this stage, all of my sections are using the same “page,” and they all work fine but one: to clarify, when I navigate to any section, the page loads— with one exception. Navigating to that section produces the behavior described. If there’s no other way to trace what Textpattern is doing with that url request, I guess I’ll keep poring over the page template until I see something amiss, but I’m not sure why it would work for requests of all other sections.

Re: "Can't open page" "Server busy" or "Dropped connection" error
I was wrong— I’ve isolated the parts of my default page that aren’t working, but I can’t tell why. Here’s the page template that seems to be locking up, stripped to essentials:
<!--

Re: "Can't open page" "Server busy" or "Dropped connection" error
If you look at your webserver error and access logs (not the logs inside TXP), do requests that end in such a blank page show up on those error/access logs?
Also, can you post your TXP diagnostics?

You use MAMP? Just try one thing: Turn off “Zend Optimizer” and see if that helps.

Thanks! Immediately I was able to load a page annotating the tag parsing error— and I think I pinpointed the problem.
Thanks again Uli! I’m very grateful for your help.
So, What does “Zend Optimizer” do? Is this something that I would ever need?

Glad my previous problems could help someone :)

Can only send you to a Wiki article on PHP accelerators
It’s probably included in MAMP to provide a development environment to be fine-tuned the closest as possible to final server environments.
