summary(table)
Hi,
Why when I do a summary on a table it cuts off the other variables? It says
Other :58 or Other: 120.
how can I get the summary for all the variables under ServLoad.Task and
Server.Load and Avg. CPU and Max.CPU?
Thanks,
summary(probF)
Reboot.Id ServLoad.Task Server.Load
Avg.CPU Max.CPU Event.Log

dovecot auth using 100% CPU
Every few days I find that dovecot auth is using all my CPU.
This is from dovecot 2.2.13, I've just upgraded to 2.2.18
strace -r -p 17956 output:

dovecot auth using 100% CPU
What do you see in the logs?
My guess is that someone is trying a brute force auth against you,

Upssched 100% CPU after updating Debian 12
After launching the command several times, with debug (posted by new code
in a new branch for the investigation) confirming that the same daemon
handles operations from the new client instances, its strace now has
numerous FDs to report after select() - so I guess it is a problem of
detecting an exit of the counterpart.

Upssched 100% CPU after updating Debian 12
Hi,
Great work Jim! I?m glad you could reproduce the problem and found a potential culprit.
Just for my own interest I restored upsshed from my backups (version 2.7.4-13) and it seems to running ok, so no big runtime changes regarding that with Debian 12. It is not hogging CPU. From the daemon log the heartbeat seems to be working ok. Only difference between the old logs (pre Debian 12 update)

Upssched 100% CPU after updating Debian 12
So... determining that FD is to be reaped proved hard. Internet lore
suggests fcntl() and poll() on the FD, but it just seems valid to them. The
errno is also usually not raised (once I saw a "111: Connection refused"
though).
So the best dumb idea so far is to bail out if we spent the whole loop (128
attempts) and only got zero-sized read replies and no errors.

open/stat64 syscalls run faster on Xen VM than standard Linux
Dear all,
When I debugged the execution performance of an application using strace, I found there are some
system calls like open and stat64 which run faster on XenLinux than the standard Linux. The
following is the output of running "strace -c /bin/sh -c /bin/echo foo" on both systems. An open
call runs averagely 109 usec on standard Linux but only 41 usecs on XenLinux. An stat64

So, got some good news: I hear(*) I managed to reproduce the problem with
current NUT master and an adapted copy of your posted configs and script :D
Experimental debugging now sounds possible.
(*) PC under the desk wails with all its cooling fans as soon as I started
the client which spawned a daemon and itself had exited:

[PATCH 00/18] rvh-upload: Various fixes and cleanups
This series extract oVirt SDK and imageio code to make it eaiser to follow the
code and improve error handing in open() and close().
The first small patches can be consider as fixes for downstream.
Tested based on libguestfs v1.41.5, since I had trouble building virt-v2v and
libguestfs from master.

Bug#588310: Xen enabled kernel cannot find the / partition
Package: xen-hypervisor-3.4-amd64 and linux-image-2.6.32-5-xen-amd64
Version: 3.4.3-1 and 2.6.32-15
Hello all,
GRUB-PC does not automatically populate Xen related parameters in
/boot/grub/grub.cfg so I added them manually (see below). All the
packages involved on my Dell PowerEdge R710 running Debian GNU/Linux

linux kernel 3.17, freeze on resume
This may not be the proper place to raise this question but I've had little luck elsewhere.
After trying again, unsuccessfully this time, to install the proprietary NVIDIA driver, I've decided to focus my efforts on the open source Nouveau driver. I've seen video drivers blamed for varying degrees of "freeze on resume" but I'm not certain that's what I'm up
