The Fedora bug to which this corresponds is caused by an overlapping memcpy() in mod_ssl. This issue was triggered by a change in glibc which meant an overlapping memcpy now causes data corruption - see bug 638477 for background. The particular change in the glibc memcpy is not present in the RHEL 6 glibc, and this issue is not known to be reproducible in the RHEL 6 httpd. Please: a) describe exactly the symptoms you are seeing, and describe how you can reproduce them. b) confirm the version of glibc you are using. Please note that bugzilla is not a support tool and customers should contact Red Hat Technical Support in the first instance with any questions or issues you are having with the software; see: http://www.redhat.com/support/process/ for more information. Symptoms :
When accessing pages through SSL, I receive sometimes :

It happens not often at the beginning, but it becomes worst if the server stays running for some time. A simple 'refresh' of the page often succeed.
Disabling "mod_rewrite" (found on forums) seems to remove the problem, but it's hard to be sure as the problem does not always occur...
Currently, I solved the problem by compiling the httpd-2.2.17 source rpm for FC13, which seems to work normally without this issue, with the exact same configuration...
GLIBC : glibc-2.12-1.7.el6_0.3.i686
Since RHEL 6.1 External Beta has begun, and this bug remains unresolved, it has been rejected as it is not proposed as exception or blocker. Red Hat invites you to ask your support representative to propose this request, if appropriate and relevant, in the next release of Red Hat Enterprise Linux. Is this still reproducible with 2.2.15-9? If you have a reproduction case with the latest updates, please re-open. |
