Crash page?

(It happens when MySQL has to query large rows. By default, memory_limit is set to small, which was safer for the hardware.)

You can check your system existing memory status, before increasing php.ini:

# free -m
             total       used       free     shared    buffers     cached
Mem:         64457      63791        666          0       1118      18273
-/+ buffers/cache:      44398      20058
Swap:         1021          0       1021

Here I have increased it as in the following and then do service httpd restart to fix the crash page issue.

# grep memory_limit /etc/php.ini
memory_limit = 512M
