Comment 4 for bug 422960

I've run tracereport.py on launchpad-trace1.log.4. Results attached. I don't know (yet :-)) how to interpret that data but hopefully it'll be useful to debug this bug.

(Some more background information if anyone is interested in running the tracereport.py script. Use the script from this branch https://code.edge.launchpad.net/~launchpad-pqm/zc.zservertracelog/trunk as the newest version can't cope with the logs generated by Launchpad)
