Re: Fatal: master: service(indexer-worker): child 493 killed with signal 11 (core dumped)

[Tim Mohlmann via dovecot]

I'm really sorry, but it was a long day yesterday. I forgot to mention
that I used alpine:edge (based on the alpine master branch) image to set
up the build environment. So there were some version changes.

dovecot --version: 2.3.3 (dcead646b)

apk info musl:

musl-1.1.20-r2 description:
the musl c library (libc) implementation

Configuration was unchanged wrt to my first mail. Maybe it's helpful to
share the build flags?

export CFLAGS="-O0"
export CXXFLAGS="$CFLAGS"

export CPPFLAGS="$CFLAGS"

export LDFLAGS="-Wl,--as-needed"

In the APKBUILD file can be found here:
https://git.alpinelinux.org/cgit/aports/tree/main/dovecot/APKBUILD and
I've modified the following:

options="libtool !strip"

subpackages="

 

     $pkgname-dbg

"

And if it is of any interest, I've done a `docker commit` on the
container and pushed the resulting image as muhlemmer/dovecot:debug.
https://cloud.docker.com/repository/docker/muhlemmer/dovecot/tags. Don't
know if its of much use by itself, without the Mailu ecosystem around.
Just in case.

Cheers!

[Tim Mohlmann via dovecot]

I've managed to re-compile the alpine packages inside the container,
creating the debug symbols and disabling compile time optimizations, as
they also disturbed the backtrace. The following output looks much more
meaningful. But unfortunately there are still some symbols missing for
lucene-core. Let me know if this is enough to work with. (It doesn't
seem to be musl after all?)

[Tim Mohlmann via dovecot]

Dear list,

We been having some issues where the indexer-worker is crashing. This
happens on production servers which are handling a slight amount of
mail, but is also reproducible by moving messages. Also, users on my
server are complaining about "Trashed" items coming back etc.

Some details:

- Dovecot 2.3.2.1 in alpine:3.8 based Docker container. As part of the
Mailu distribution. (https://github.com/Mailu/Mailu)

- I've first seen this issues on my production server, which stores mail
on GlusterFS

- I've been able to reproduce running the Docker container on a Virtual
machine, using local storage.

- There is another Mailu user reporting the same problem on a different
VM provider / disk infrastructure: https://github.com/Mailu/Mailu/issues/751

- Libc: musl-1.1.19-r10

Output of dovecot -n:

Well, I am honestly sorry then for having caused another problem for
you while trying to help solving someone else's problem.
