Topic: Any recent changes that could cause increased memory consumption?
We have an old server running php 5.4 (I know!). After a recent update apache has suddenly been using a lot more memory and we can't figure out why. This coincides with a puppet run (these are regular) which amongst other things has upgraded/installed packages, and I'm wondering about the possibility/probabily of any of the recent backports contributing to this?
The relevant yum log is:

After this, suddenly apache is using much more memory and we're having to reboot server every 2 days!
I've since removed pecl zip (as that server doesn't need it) and datadog (since we don't need it necessarily) just on the offchange it would help, but of course it doesn't.
