It was observed before the recent reboot that sourceware was exhibiting a high level of disk activity, contributing to a high overall load, resulting in things like dropped anonsvn/cvs connections etc. The nature of disk activity is that it's difficult to point the finger at the precise cause, but the mercurial script that pulls from svn seemed to be cropping up a lot. So if you're going to be monitoring mercurial, please also consider its effect on disk, not just CPU. This won't show up in 'top' etc. For now though, the load seems lower, and I couldn't say for definite what the difference is, but I do note the mercurial scripts no longer seem to be running (since the reboot). Have a look at http://sourceware.org/mrtg/summary.html and in particular note http://sourceware.org/mrtg/pageio.html and how it changes at start of week 20. I don't know whether, if or how that corresponds to when mercurial (or the mercurial pull from svn script) started operation.
