503 Error when viewing PHP INFO with Xcache installed

[skooboy]

CentOS 6.6 x86_64
WHM/Cpanel 11.46.1
LiteSpeed 4.2.20 Enterprise 2-CPU
PHP 5.6.4
Xcache 3.2.0

I go to view the PHP INFO in the admin panel of my Invision Power Board and it immediately gives a 503 Service Unavailable error. This never happened before and only stated after compiling PHP with Xcache.

Here's the Xcache settings:

Any ideas? Thanks.

I just noticed this in stderr.log at the same time as the 503 error.

you need to rebuild your PHP binary, pdo_sqlite extension is broken. or take out pdo_sqlite.so out from the php.ini .
