I decided to make a new thread on this seeing that I found many old ones scattered about with no resolution: Here are old threads regarding the same/similar issue http://lists.xensource.com/archives/html/xen-users/2007-08/msg00135.html http://lists.xensource.com/archives/html/xen-users/2007-07/msg00624.html Old bug reports of the issue: http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=542 http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=1038 In 1038, spam@abma.de _incorrectly_ reports it is fixed in 3.1.1 -- Not only can I find any evidence of this, I can EASILY reproduce the crash over and over with 3.1.3-rc2. I have a dev. Xen box available for anyone who wants access for stack traces, ect. Unfortunately I myself do not have enough knowledge to find the problem myself, however I am available to instruct on how to produce the bug, run stack traces, help organize this effort, and provide unrestricted access to this dev machine if needed. -- Randy McAnally Fast Serv Networks, LLC 619-819-8252 x201 619-819-9443 fax
