12 requests where I was able to note that the output buffer failed out of 142
requests to that specific script.
As a whole I average 150,000 PHP requests per day

I guess there is some kind of memory problem.
What modules are loaded in your web server and SAPI?
<?php
var_dump(get_loaded_extensions(), php_sapi_name());
?>
or paste phpinfo() output.

How many requests a day you have?

@mike at php.net Yes that is the bug I'm reporting - the php.ini setting does
not
start the output buffer on every request.

Looks like when this is logged, there actually is no output buffer active, so
ob_get_length() returns false.

I also tried the settings of On and 1.
I also understand that #!/usr/bin/php means nothing to output buffering but is
output that
I want to capture if the php file is being run from a browser and discard.
>From what I understand that is not how the output buffering works. The way I
>understand it
the output buffer fills then dumps everything when it is full. In this instance
before the
output buffer fills I want to discard the first 15 characters because it will
corrupt any
binary files that the browser is trying to download.
Based on the test script attached ob_get_length() should ALWAYS return 15
characters -
however at least 12 times a day PHP fails to start the output buffer and I get
the error
shown.

"#!" does not have special meaning for Web server SAPI.
I think you are sending data larger than output buffer size. Then this is the
way supposed to be.
output_buffering=On or 1 is special. It enables unlimited buffering. Anything
other values set buffer chunk size and PHP tries to send data larger than chunk
size.
Check your buffer size (i.e. output_buffering setting of php.ini file)
I guess you have very small output_buffering. Old output buffer increases size
automatically, IIRC. New output buffer does not increase buffer size.
