PHP fopen "failed to open stream: resource temporarily unavailable"

Question

EDIT: Austin below in the comments resolved my issue. How do I close the question since that is the answer?

I have the following simple code to open/write to a query file on my server. I've checked permissions and even set +rw for all users on the query file, yet I still get the error

failed to open stream: resource temporarily unavailable

in my apache error log.

I'm not really sure what I can do to alleviate this issue, thoughts?

<?php 
// filepaths
$queryFile = '../query/query.txt';

// get query
$query = $_GET['searchBox'];

// open and write query to query file
$fh = fopen($queryFile, 'X') or die("Can't open file");
fwrite($fh, $query);
fclose($fh);

Solution 1

It could only be one of a few things:

• The PHP process is out of memory, file handles, or similar
• The PHP environment's own limitations are exceeded somehow
• The file itself has some limitation, such as a SELinux (Security Enhanced Linux) restriction.

To determine which it is, try opening the file outside PHP. Temporarily alter the script to open a different file. Look at what else the script does to validate whether it could possibly be running out of file handles, etc.

Solution 2

What does is_file($queryFile) and is_writable($queryFile) reveal? Maybe you are not in the correct working directory?

It's not an answer, it should be a comment.
