Create Account - a fatal error or timeout occurred while processing this directive

Hi - just noticed this today (never came across it before), but when I went to "Create an Account" in WHM, I keep getting an error message...

a fatal error or timeout occurred while processing this directive

I've searched on this forum - tried a yum upgrade, but that doesn't seem to have fixed it.

I've included the last 1000 lines of the error_log here.

Let me know if you need more info.

Running CENTOS 6.9 virtuozzo v68.0.36 which I believe is the most current version.
