PHP Fatal error

Question

For some reason Apache/PHP is throwing these errors in the error_log. I can't figure out what is causing it?

[Wed May 06 16:39:33.056497 2015] [:error] [pid 14857:tid 140714977302272] [client 165.196.202.10:3143] PHP Fatal error: Unknown: Cannot find save handler '/var/lib/php/wsdlcache' in Unknown on line 0, referer: http://web.$ [Wed May 06 16:43:34.248044 2015] [:error] [pid 15111:tid 140715103180544] [client 163.248.244.189:25966] PHP Fatal error: Unknown: Cannot find save handler 'tcp://74.221.216.88:11211?persistent=1&timeout=1&retry_i$ [Wed May 06 16:45:04.160496 2015] [:error] [pid 15174:tid 140715375916800] [client 163.248.244.76:32613] PHP Fatal error: Unknown: Cannot find save handler 'tcp://74.221.216.88:11211?persistent=1&timeout=1&retry_in$ [Wed May 06 16:45:33.577941 2015] [:error] [pid 15302:tid 140715134650112] [client 162.127.23.29:52057] PHP Fatal error: Unknown: Cannot find save handler 'tcp://74.221.216.88:11211?persistent=1&timeout=1&retry_int$ [Wed May 06 16:47:04.304594 2015] [:error] [pid 15365:tid 140714998281984] [client 198.236.95.97:22866] PHP Fatal error: Unknown: Cannot find save handler 'tcp://74.221.216.88:11211?persistent=1&timeout=1&retry_int$ [Wed May 06 16:50:31.683150 2015] [:error] [pid 15680:tid 140715218568960] [client 206.208.218.40:40735] PHP Fatal error: Unknown: Cannot find save handler 'tcp://74.221.216.88:11211?persistent=1&timeout=1&retry_in$ 

According to "php -i | grep session" the same handler for sessions is right.

session.save_handler => memcache => memcache session.save_path => tcp://74.221.216.88:11211?persistent=1&weight=1&timeout=1&retry_interval=10 => tcp://74.221.216.88:11211?persistent=1&weight=1&timeout=1&retry_interval=10 

Any ideas how to fix this? OS: CentOS 7 64Bit Http: Apache 2.4 event mpm PHP: php-zts

Thanks!

Check whether is memcache daemon is running and port 11211 is listening and awailable by filrewall. Also you should check memcache module in PHP(loaded or not)
