[PATCH 1/3] Add a core_pattern debug command The first patch is just a rework of Rich's earlier core dump patch. It turns it into a debug subcommand so it can be called at any time. This also has the advantage of explicitly labelling an extremely untidy API as debug. [PATCH 2/3] Call sync after guestfsd exits The second patch seems to be required for cores to be dumped reliably. I was able to

These two patches are probably not completely independent, but separating them is a lot of work. With *both* patches applied, all the tests and extra-tests pass. That's no guarantee however that there isn't a mistake, so I don't think this patch is a candidate for the 1.16 branch, until it's had a lot more testing in development. Rich.

Hi, this patch series improves the way /usr filesystems are handled: tag them appropriately, so later on we can find them and merge results they contain directly back for the root filesystem. The series includes also a new private debug API, and its usage to fix the resolution of /dev/mapper/.. devices found in fstab; without it, LVM /usr filesystems are not recognized as belonging to their

With this, "make syntax-check" runs a few more tests, all passing. >From febff9d2a35c4f40abbaf8943146476bdeac671e Mon Sep 17 00:00:00 2001 From: Jim Meyering <meyering at redhat.com> Date: Tue, 4 Aug 2009 13:49:19 +0200 Subject: [PATCH 1/8] build: remove more files added by ./autogen.sh * po/LINGUAS: Remove file. * po/Makefile.in.in: Likewise. * po/Makevars: Likewise. *

After the previous refactoring, we are able to link the daemon to common/utils, and also remove some of the "duplicate" functions that the daemon carried ("duplicate" in quotes because they were often not exact duplicates). Also this removes the duplicate reimplementation of (most) cleanup functions in the daemon, since those are provided by libutils now. It also allows us in

Useful for tracking down segfaults in the daemon. This is not upstreamable right now. Example usage: $ ./run guestfish -v -x -a /dev/null run : debug segv "" [...] libguestfs: trace: launch = 0 libguestfs: trace: debug "segv" "" guestfsd: main_loop: new request, len 0x34 Program received signal SIGSEGV, Segmentation fault. debug_segv (subcmd=0x4687050

blkid(1) (or actually, libblkid) seems to handle file system labels up to 127 characters. Considering that btrfs labels can be up to 255 characters, this means long labels are not read correctly (i.e. get truncated) by blkid. Get the file system type, and if btrfs is available invoke `btrfs filesystem` to get the label of btrfs file systems. --- daemon/blkid.c | 6 ++++++ daemon/btrfs.c | 24

What's /proc/sys/kernel/core_pattern set to for you? For me it is % cat /proc/sys/kernel/core_pattern core which will drop a core file in the working directory of the process. On 19/01/2018 12.56, Frank Wall wrote: > Is there something I could do to trigger the creation of core files?

I think were getting closer: I did: - I edited /etc/default/asterisk to include : AST_USER="root" AST_GROUP="root" # systemctl daemon-reload # systemctl start asterisk # ps aux | grep asterisk root 3602 7.1 2.5 60332 26012 ?

Does any one know how to change astmanproxy to be able to a) compile without optimisations b) dump a core I've had it crash several times over the past couple of months, but there is no way to debug what's going on. I like the way a core is produced when (if!) * crashes, and would like to have the same thing on astmanproxy. Thanks Julian

Please connect gdb to the hung process and get a stack trace to find out where it's hanging. 'strace -p ...' output might also be enlightening, if it is not hung but doing
