Cpanel PHP error

[aag73]

Since a few days ago, all of my Cpanel servers are reporting this on the /usr/local/cpanel/logs/error_log.

Just wondering if Cpanel is aware of this and a possible solution is in place.

I had a similar problem recently, which seemed to start immediately after server updates. Rebooting fixed it. I suspect a disagreement between libraries and kernel.
