Hi, I''ve been struggling with Xen for a little while not and seem to have circumnavigated a number of issues ... but now I''m stuck. I have a box with 4 x 2.8G Xeon cores and 6Gb of RAM. It''s running ~ 9 DomU''s which are all doing different things. Every now and again (random, 10 mins to 4 hours) the Dom0 will "pause". Effectively one or more processes will enter D state and stay there for 5 minutes or so, and these in turn are likely to lock up other processes. (the first ones to go are always network related, either glusterfsd or mysql cluster storage) After a while it all unwinds and carries on as normal .. and in the meantime the DomU''s seem happy to continue irrespective of the Dom0''s lockup. It smells like a network related kernel parameter / table being filled and waiting for a timer to expire ... Anyone got any ideas ? tia Gareth. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
