Bug#838491: linux-image-4.7.0-0.bpo.1-amd64-unsigned: extreme load averages and over 2000 kworker threads
Package: src:linux
Followup-For: Bug #838491
Dear Maintainer,
* What led up to the situation?
upgrade kernel and systemd to the version proveded in jessie-backports
* What exactly did you do (or not do) that was effective (or
ineffective)?
during normal usage (slurm cluster node):
load average: 1290.54, 513.19, 466.29
the load 5 peaks reache 2000
ps aux | grep kworker | wc -l
4188
I followed the Debugging instruction of
https://raw.githubusercontent.com/torvalds/linux/master/Documentation/workqueue.txt
echo workqueue:workqueue_queue_work > /sys/kernel/debug/tracing/set_event
cat /sys/kernel/debug/tracing/trace_pipe > out.txt
after a vew seconds:

Bug#737960: ganglia-monitor: gmond segfault
Package: ganglia-monitor Version: 3.6.0-2 Severity: normal Dear Maintainer, I am replacing an old ganglia setup running on debian lenny which consists of 4 clusters. Therefore I changed the init.d script to run 4 instances of gmond. I also configured it to use rrdcached. The main difference to the old setup is that I activated sFlow support and that I changed from tmpfs to rrdcached. I changed the configuration of the clients to send to both the old and the new server. During the last Day I got 3 segfaults: Feb 6 09:53:52 web05 kernel: [232710.661591] gmond[24775]: segfault at cc000928 ip 7f6ad56f2f21 sp 7f6ad2a9bfb8 error 4 in libc-2.13.so[7f6ad5672000+182000] Feb 6 10:08:28 web05 kernel: [233589.004172] gmond[24314]: segfault at 6c0008d8 ip 7f6274ab7f21 sp 7f6271e60fb8 error 4 in libc-2.13.so[7f6274a37000+182000] Feb 7 07:16:52 web05 kernel: [309692.562475] gmond[28971]: segfault at 84000928 ip 7fcf912e2f21 sp 7fcf8e68bfb8 error 4 in libc-2.13.so[7fcf91262000+182000] All 3 segfaults could be related to sFlow. I configured sFlow on some Windows hosts. It is possible that the segfaults occurred when a Windows host is booted bat I am not completely sure about that. -- System Information: Debian Release: 7.4 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'proposed-updates'), (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 3.2.0-4-amd64 (SMP w/8 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages ganglia-monitor depends on: ii adduser 3.113+nmu3 ii libapr1 1.4.6-3+deb7u1 ii libc62.13-38+deb7u1 ii libconfuse0 2.7-4 ii libexpat12.1.0-1+deb7u1 ii libganglia1 3.6.0-2 ii libpcre3 1:8.30-5 ii zlib1g 1:1.2.7.dfsg-13 ganglia-monitor recommends no packages. ganglia-monitor suggests no packages. -- Configuration Files: /etc/ganglia/gmond.conf changed [not included] /etc/init.d/ganglia-monitor changed [not included] -- no debconf information -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe.

If you create an empty database with kdb5_util, the propagation will then work correctly, but it won't cope with not having a database at all. It will presumably be fixed in a later release, but as there isn't an upstream fix yet (so far as I know) I'm afraid lenny is likely to release with that problem. :/ Yeah, thanks replication works now.
