Ensure that you have PHP 'opcache' module enabled exactly once in /etc/php5/fpm. PHP really does not like to have two instances of opcache and throws various similar errors.

[iGuy5]

Interesting. I removed opcache.ini and restarted php5-fpm and I did not receive the error. Re-enabled opcache.ini and I received the error again. inside opcache.ini I have the following

; configuration for php ZendOpcache module
; priority=05
zend_extension=opcache.so

opcache.enable=1
opcache.enable_cli=1
opcache.memory_consumption=128
opcache.interned_strings_buffer=8
opcache.max_accelerated_files=4000
opcache.max_wasted_percentage=5
opcache.use_cwd=1
opcache.validate_timestamps=1
opcache.fast_shutdown=1

I looked inside /etc/php5/fpm/php.ini and while I see opcache all lines are disabled...

any insight on what I'm doing wrong here ?

[rraptorr]

You have enabled opcache twice or more. Simply grep your entire configuration and ensure that you have only one zend_extension line.

Thank you sir. I had

/etc/php5/fpm/conf.d/20-opcache.ini
and
/etc/php5/fpm/conf.d/5-opcache.ini

All fixed now. Again thank you kindly for helping.
