Daniel Veillard:
As was reported on IRC and found by Dan Berrange, sometimes Xen event handling could start to go wild and block processing of requests in the daemon.
The fault at least on libvirt side is that we didn't filter out non read/write event requests when asking for watches in the xenstore. The provided patch seems to work for the person who reported the original problem,
It seems to work, although it may not have solved my problem: http://dpaste.com/13740/ There are five backed-up pause requests on this server, and it seems that four of them may be stuck in the xenstore code (apologies for the lack of debugging symbols on there. I really ought to get a debug package built, or haul over an unstripped version of libxenstore.so 3.2 from somewhere). -- Information gladly given, but safety requires Nick Moffitt avoiding unnecessary conversation. nick@zork.net
