Hi, do not know if this applies to your problem, but I had the same error a few months ago, in a server acting as 'normal' http server, not a proxy setup. I'm using MPM worker and an httpd, 2.4.6 from CentOS, and had to set MaxRequestsPerChild 0 in the worker configuration. On CentOS 7 it is under /etc/httpd/conf.modules.d/00-mpm.conf. Maybe this helps in your case too.
