 +==== CloudLinux Imunify360 error ====
 +
 +Check ''​stderr.log''​. It shows:
 +<​code>​
 +  *** Error in '​lsphp:/​home/​ukrainia/​public_html/​index.php':​ malloc(): memory corruption (fast): 0x00007fa380d45e40 ***
 +  ======= Backtrace: =========
 +  /​lib64/​libc.so.6(+0x7f574)[0x7fa37c07f574]
 +  /​lib64/​libc.so.6(+0x82c90)[0x7fa37c082c90]
 +  /​lib64/​libc.so.6(__libc_malloc+0x4c)[0x7fa37c0857dc]

 +</​code>​
 +
 +If you try the following:
 +
 +**/​opt/​cpanel/​ea-php54/​root/​usr/​lib64/​php/​modules>​** ''​mkdir backup''​
 +
 +**/​opt/​cpanel/​ea-php54/​root/​usr/​lib64/​php/​modules>​** ''​mv i360.so backup/''​
 +
 +**/​opt/​cpanel/​ea-php54/​root/​usr/​lib64/​php/​modules>​** ''​ls -l i360.so backup/''​
 +
 +You will get this result:
 +
 +  ls: cannot access i360.so: No such file or directory
 +  backup/:  ​
 +  total 88
 +  -rwxr-xr-x 1 root root 86568 Nov 15 12:37 i360.so
 +
 +The issue is fixed by disabling CloudLinux'​s ''​i360.so''​. This is a CloudLinux bug. Please be aware that it may have been fixed by the CloudLinux team by the time you read this wiki, but it was a cause of 503 errors at one time.
