Do you get this same behavior when running the standard RHEL5 kernel? Just trying to initially narrow things down to kernel vs glibc. There is not enough information contained in this bug report for us to understand the problem and attempt to resolve. Please provide the test case and accompanying descriptive information. I've looked at the problem. After ignoring the misleading subject I've found a problem which is likely the cause for the issue which is observed. We have to be less optimistic about the state of memory in arenas other than the main arena when madvise is used. The upstream glibc cvs contains a fix. Testing with the next rawhide build when it's done would be appreciated. Just checked to see where specifically the package can be found. The answer was that this package has not yet been built and provided externally. This bugzilla will be updated when the new package is available. Here's some instructions on accessing the Fedora rawhide to get the latest available packages. Easiest is to download from koji. Go to http://koji.fedoraproject.org/koji/, search for glibc (in the search field), select the most recent version, and then download the individual RPMs I'll try the fix either with rawhide or the cvs libc and let you not if the issue is gone. Backported in glibc-2.5-20. 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. qe_ack+ for rhel5.2 we'll need some testcase (or at least some testing hints), or verification from Sun (comment 6) I've tried the 2.7 glibc from: http://koji.fedoraproject.org/koji/buildinfo?buildID=31131 No more crashes. The bug is fixed as far as I can tell. An advisory has been issued which should help the problem described in this bug report. This report is therefore being closed with a resolution of ERRATA. For more information on the solution and/or where to find the updated files, please follow the link below. You may reopen this bug report if the solution does not work for you. http://rhn.redhat.com/errata/RHBA-2008-0083.html |
