Subject Stacktrace in whirr.log
Date Fri, 05 Aug 2011 16:08:10 GMT
In whirr.log, someone I work with has this stacktrace when running
whirr launch-cluster or destroy-cluster (see bottom).
It occurs even with a minimal ec2 cluster (1 noop).

>From the stacktrace I gather that this happens while parsing an
'ec2dim' query response. I don't think it does any harm, but I thought
someone would like to hear about it.

Regards,
Karel
