[rt-users] Very high Apache CPU usage after upgrading to 4.0.0

After updating to 4.0.0, apache will sometimes spawn a process that uses
100% cpu usage for a few seconds, and noticeably slows down the entire
system.

What could be causing this, and what would the best course of action to
debug it be?

I've tried a clean install (with my custom config, but no plugins) which
also has the same issue. 100% cpu usage from Apache, causing the system to
screech to a halt.

Apache 2.2.14 (Ubuntu)

The only thing I'm getting logged is the following warning:

Unable to recognise encoding of this document at
/usr/share/perl5/XML/SAX/PurePerl/EncodingDetect.pm line 100.
(/usr/share/perl5/XML/SAX/PurePerl/EncodingDetect.pm:100)
