...N maintainers, R core team, Here are some suggestions to prevent some issues I found in several packages on CRAN. Some of these issues have been reported to their maintainers, but still I believe it would be desirable to enforce these on CRAN or in the corresponding R CMD. - Checks for undeclared sysreqs. There are packages that do not declare some system requirement. E.g., bioacoustics requires fftw and soxr, but no sysreqs are declared; ijtiff links agains jpeg, but it's not declared; there are a handful of packages linking against GSL and not declaring it, such as BayesSAE, BayesVarSel, bnp...

As previously stated this had more problems because of differing output of xl list -l, which appears to be employed by xendomains.

Hi, this says that opensolaris only requires 512MB ram: http://dlc.sun.com/osol/docs/content/IPS/sysreq.html This says 1GB ram and a 64bit processor are recommended: http://www.solarisinternals.com/wiki/index.php/ZFS_Best_Practices_Guide#Memory_and_Swap_Space Am I going to have problems if I run opensolaris and zfs at the minimum requirements? -- This message posted from opensolaris.org

I am using CentOS 5.6 as a KVM host. My guests are running CentOS 5.6 with the only console being a virtual serial console. The guests are configured so magic-sysreq can be used to debug kernel issues. However, in order to send magic-sysrq from a serial port, I need to send a break. How does one send a break on the virtual console serial port provided by KVM/libvirt to guests? Thanks, David

...Maxtor disk with about 12G free. The system locks up hard (no ping, no capslock light) after a while. Different place every time. Built 2.4.20 with ext3 debugging. Set debug level to 3--no lockup. While writing this, reran test with debug level 2--locks up. I'm going to build with the magic sysreq key and see if any further elucidation is possible. -- David Poole "Setting a bologna sandwich on fire does dpoole at mbuf dot com not constitute cooking." - Get Fuzzy

Hi, does Centos-5 support the GFS filesystem and the RedHat cluster suite? I did not find anything in the FAQs.

When I hang-up the system, then the screem is black. But the power light is brightness. and the disk light is bright sometimes. When I press any key, the screem is still black. Only can do is to press down power button for several seconds to power off the notebook. Is there the bug of the Centos? -------------- next part -------------- An HTML attachment was scrubbed...

I begin to find a way that help me investigate fifo: SCHED_ERROR 0a [CTXSW_TIMEOUT] errors.

[mod: This is the second time in a week that someone asks this question: is it a new attack? It sure looks to me like "userland" has completely locked up, but that the kernel is still working. As an isolated case, my diagnosis is: You probably have a bad block in your /bin/login program or something like that. When two people report this in a week, it's starting to become unlikely

I have many different centos machines that are hanging regulary. I believe this is due to something our application is doing - not a centos specific problem. When the machines hang, there is no access to the console or remote access(ssh, rsh, etc). Any tips on debugging this issue? It is becoming quite a show stopper as we migrate our product from Solaris to Linux. tia, FYI - The

In the past I've found that the console may have blanked (due to time) and when the system locked up/hung it won't unblank. Booting with "consoleblank=0" on the kernel command line will ensure that whatever is printed to the console (oops, panic, etc) will be there for you to see when you connect. I've had intermittent success in that type of situation with the SysRq key(s),
