Hi, I'm trying to figure out the cause of a soft lockup I experienced: Mar 29 09:38:24 pstn1 kernel: BUG: soft lockup - CPU#0 stuck for 10s!

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I have a 6.3 guest running on a 6.3 host and the output from top seems strange to me. At least I did not expect this. While in the guest on core is busy with i/o the host seems idle. Does anyone know why it is this way? See the output from top below, first the one from guest, then host. top - 14:12:35 up 12 min, 1 user, load average: 2.76,

Hello I've got small PBX (30 simultaneous connections) based on asterisk (1.6.2.6), which uses Stargate 2N ISDN to GSM gate.

Hi Konrad I encountered a bug when trying to bring offline a cpu then online it again in HVM. As I''m not very familiar with HVM stuffs I cannot come up with a quick fix. The HVM DomU is configured with 4 vcpus. After booting into command prompt, I do following operations. # echo 0 > /sys/devices/system/cpu/cpu3/online # echo 1 > /sys/devices/system/cpu/cpu3/online With

Hi all, we've started receiving complaints from users that seemingly use more quota than they actually have. We noticed that these users have (in some cases many) .nfs files in their mailspool. Some of our admins checked their own dirs, and noticed them there as well. This could of course be unrelated to dovecot (kernel issue, netapp issue) but maybe somehow has an idea about if dovecot could

Hi list, I've recently managed to install CentOS 4.4 on an Apple Mac Pro. Functionality-wise everything works great, but when trying to benchmark the system, I don't get stable runtimes, they differ by more than 30%. For example a benchmark run with our PDE solving code takes between 500 and 800 s on the completely unloaded machine. Suspicious kernel output (complete output attached):

I have updated my laptop to 7.4 CR this morning and found that there have been a lot of logs on two fronts for the first time. 1.

Hey all, I upgraded some servers today from Debian Lenny to Debian Squeeze, and after the upgrade I started getting dovecot crashes. I was on 2.0.13 but got these there as well, and hoped upgrading to 2.0.16 would help. It didn't. Anyone have an idea?

This is the strangest problem I have seen. I have a lustre filesystem mounted on a linux server and its being exported to various alpha systems. The alphas mount it just fine however under heavy load the NFS server stops responding, as does the lustre mount on the export server. The weird thing is that if i mount the nfs export on another nfs server and run the same benchmark (bonnie) everything

Hello all. I have a supermicro 16 bay box with a LSI 9211-8i card. We use it for temp data storage, and we wanted to try the l4z compression. After updating the source tree to r247839: and doing a make buildworld cycle all works fine. But at boot time we get some warnings. make_dev_physpath_alias: WARNING - Unable to alias gptid/281951f4-a996-11e1-83eb-00259061b51a to enc at
