"EnableMMAP off" could definitely help here.

underscores are not allowed in host names by RFC and many things will
AFAIK, underscores are forbidden from being part of a host name as per
RFC 1123 Sec 2.1/RFC 952 (Assummptions Sec 1)
It's also spelled out in RFC 3986:
"
A registered name intended for lookup in the DNS (...)
consists of a sequence of domain labels separated by ".",
each domain label star
Another 2.4.25 regression reported from a Fedora user is that
underscores in hostnames are rejected by default now. I couldn't see a
specific discussion of this, was it deliberate?

Hi all!
As we're seeing more and more https on ftp.acc.umu.se I've noticed
that the number of threads listed as state W in server-status has
skyrocketed.
From 2-4 threads busy using http we're talking 70-100 threads for the
same bandwidth when the machine is pushing a mighty 2.7% average CP

I wonder if the attached patch (related to mod_ssl and proposed for
another segfault report) could help in your case.
Would you mind give it a try?
Thanks,
