This request was evaluated by Red Hat Product Management for inclusion in a Red Hat Enterprise Linux maintenance release. Product Management has requested further review of this request by Red Hat Engineering, for potential inclusion in a Red Hat Enterprise Linux Update release for currently deployed products. This request is not yet committed for inclusion in an Update release. Comment #10 in bug 240009 refers to this mailing list thread http://lists.xensource.com/archives/html/xen-devel/2008-01/msg01147.html About QEMU crashes under high load. THis resulted in the following patch: http://xenbits.xen.org/xen-3.1-testing.hg?rev/df56245d48f5 which fixes one known race condition. I can't say for certain whether this bug reporter is hitting this particular race condition, but it certainly a likely candidate & an race which should be fixed. In absence of any other explanation for the crashes, I'd recommend we apply the upstream patch I reference above and see if QEMU remains crash-free under load. This request was previously evaluated by Red Hat Product Management for inclusion in the current Red Hat Enterprise Linux release, but Red Hat was unable to resolve it in time. This request will be reviewed for a future Red Hat Enterprise Linux release. This request was evaluated by Red Hat Product Management for inclusion in a Red Hat Enterprise Linux maintenance release.

This request is not yet committed for inclusion in an Update release. This bug can probably be closed as a DUP of https://bugzilla.redhat.com/show_bug.cgi?id=250988 Yes, most likely. However, I would like to leave it open just until I get another report of whether this patch works for a customer. Assuming that is successful, we can then close this out as a dup. Chris Lalancette In the past I've hit this bug quite frequently and I've been able to reproduce it simply by restarting multiple Windows DomU at the same time on a machine with many other DomU (24 of them). After installing xen-3.0.3-68.el5 I'm no longer able to reproduce the problem. On the basis of the confirmation in comment #21, i'm closing this as a dup of bug 250988. If someone manages to get this problem to recur with xen >= 3.0.3-68.el5, then open a new bug with a reproducable test case *** This bug has been marked as a duplicate of bug 250988 *** |
