Description
Changed the settings as below:
memcached.sess_lock_wait_min = 150
memcached.sess_lock_wait_max = 150
memcached.sess_lock_retries=2000
to fix "session_start(): Unable to clear session lock record" issue and started getting the below error:
*** Error in `/usr/sbin/httpd': free(): invalid pointer: 0x00007f501f999800 ***
