PHP Startup: Unable to load dynamic library

Has anyone else come across this repeated issue in their error logs? Mine is full of these two lines repeated (over 688,000 counts in just under a month):

[15-Jan-2016 08:18:27 America/Chicago] PHP Warning:  PHP Startup: Unable to load dynamic library '/opt/php54/lib/php/extensions/no-debug-non-zts-20100525/ixed.5.4.lin' - /opt/php54/lib/php/extensions/no-debug-non-zts-20100525/ixed.5.4.lin: cannot open shared object file: No such file or directory in Unknown on line 0

Does anyone know how you would go about fixing it?

Apparently it’s something to do with ‘Zend’. I have the following lines at the end of my php.ini file:

;[Zend]

;zend_loader.enable=1
; Disable license checks (for performance reasons)
;zend_loader.disable_licensing=0
; The Obfuscation level supported by Zend Guard Loader. The levels are detailed in the official Zend Guard Documentation. 0 - no obfuscation is enabled
;zend_loader.obfuscation_level_support=3
zend_extension = "/opt/php54/lib/php/extensions/no-debug-non-zts-20100525/ZendGuardLoader.so"
;extension=pdo.so
;extension=pdo_sqlite.so
;extension=sqlite.so
;extension=pdo_mysql.so

extension=imagick.so
;extension=magickwand.so
extension="ixed.5.4.lin"

Any help is appreciated ??
