what does the error message 'Operation now in progress' mean?

Question

When trying to open a file using this command:

$fd = fopen('majestic_files/majestic_record.txt','w');

I get the following error message:

<b>Warning</b>:  fopen(majestic_files/majestic_record.txt) [<a href='function.fopen'>function.fopen</a>]: failed to open stream: Operation now in progress in

What does it mean, and how do I fix it?

Answer 1

This occurs when there is an outstanding blocking operation.

In this context, the error implies that another process has a lock on the file, most likely due to the file being open and written to by whichever process holds the lock.
