Upgrade to PHP 5.4.6 failed

[theRKF]

I was running 5.3.15 and debating between moving to 5.3.16 or 5.4.6, so I thought I'd try both.

5.3.16 went without a problem.

On the other hand, as soon as I switched the symlink to point to the 5.4.6 version of PHP all sites ceased to load - even with a restart of LiteSpeed.

Is there any known compatibility issue with LiteSpeed 4.1.13 and PHP 5.4.6?

FYI: Here's my configure command, in case the settings matter
