Does anyone know if tests are being added to catch these issues?
> HP's official support for Red Hat Enterprise Linux 3 (RHEL 3) on
> ProLiant servers was originally planned for the end of November or the
> first week of December. The ISS Linux Engineering team has uncovered
> several critical problems with Red Hat Enterprise Linux 3 that is
> causing HP in delaying our official support for RHEL 3 on ProLiant
> servers. Additionally, ISS is pulling the RHEL 3 support software
> from the SmartStart 7.00 release and will provide the software to the
> web once all the critical issues are resolved.
> The first critical issue is that System V resources are not being
> locked appropriately by the kernel which can result in a system hang.
> IBM also noticed this problem and reported it to Red Hat. Red Hat is
> working on releasing a fix (kernel errata) for this problem in January
> 2004. We have tested a preliminary fixed kernel that Red Hat provided
> us and it does appear to resolve the System V resource locking issue.
> The second critical issue is with pthreads. A threaded application
> that exits normally may cause the system to hang or even panic. Since
> our Management agents utilize threads, customers running our
> management software or other threaded applications are exposed to this
> At this time, we cannot recommend that customers deploy production
> level systems with Red Hat Enterprise Linux 3 due to the severity of
> the issues that we've uncovered. We are working to isolate the cause
> of the pthread exit issue and will be working with Red Hat to
> implement a resolution.
