Subject RE: [hudson] archive phase problems

Here is another unrelated example I was talking about.

https://hudson.apache.org/hudson/job/Ant_BuildFromPOMs/buildTimeTrend

So, more than doubled in the last 3 days compared with other build times.

Note as I mentioned before, this is not tied to just one machine, but
both Ubuntu slaves and the Solaris slave exhibit this behaviour, the
same I stated for the archives builds sebb mentions. 

So, not tied to a particular machine means not disk related. (Surely?)
