Hi,

If we use sieve redirect under dovecot 2.3.7.2 we end up with

Oct 04 03:30:31 dockerhost docker[12154]: 2019-10-04T03:30:31 53ac2ae27650 postfix: 0605F207B0F36: to=xxxx@xxxx.xx, relay=127.0.0.1[127.0.0.1]:10024, delay=1.5, delays=0.36/0/0/1.1, dsn=2.0.0, status=sent (250 2.0.0 from MTA(smtp:[127.0.0.1]:10025): 250 2.0.0 Ok: queued as 6FC89207B0F38) Oct 04 03:30:31 dockerhost docker[12154]: 2019-10-04T03:30:31 53ac2ae27650 postfix: 6FC89207B0F38: to=xxxx@xxxx.xx, relay=dovecot, delay=0.31, delays=0.05/0/0/0.26, dsn=4.3.0, status=deferred (Command died with signal 11: "/usr/libexec/dovecot/dovecot-lda")

I can't readily reproduce it with the information available so far. Do you have the opportunity to obtain a GDB backtrace? You can e.g. run LDA manually at the command line with the same arguments and message input Postfix provides and wrap it in GDB if you can reproduce the crash.

Your configuration may also help (output from dovecot -n)

Stephan.

Hi Stephan,

I managed to get GDB, I hope this one helps. If not I can send the config too, but exactly same config works with 2.3.6.

You don't have the debug symbols for Dovecot installed. Usually, your system will have a separate package for that. On Debian, it is called dovecot-dbg.

Hi,

If we use sieve redirect under dovecot 2.3.7.2 we end up with

Anyone else already had this problem or you know how to fix it?

I can't readily reproduce it with the information available so far. Do you have the opportunity to obtain a GDB backtrace? You can e.g. run LDA manually at the command line with the same arguments and message input Postfix provides and wrap it in GDB if you can reproduce the crash.

Your configuration may also help (output from dovecot -n)

Do you have the opportunity to build Dovecot yourself, thereby including the debug symbols?

Hi Stephan,

I managed to get GDB, I hope this one helps. If not I can send the config too, but exactly same config works with 2.3.6.

You don't have the debug symbols for Dovecot installed. Usually, your system will have a separate package for that. On Debian, it is called dovecot-dbg.

I can't readily reproduce it with the information available so far. Do you have the opportunity to obtain a GDB backtrace? You can e.g. run LDA manually at the command line with the same arguments and message input Postfix provides and wrap it in GDB if you can reproduce the crash.

Your configuration may also help (output from dovecot -n)

I think alpine does not have that

What else would help? strace?

Do you have the opportunity to build Dovecot yourself, thereby including the debug symbols?

Stephan.

Hi Stephan,

I managed to get GDB, I hope this one helps. If not I can send the config too, but exactly same config works with 2.3.6.

You don't have the debug symbols for Dovecot installed. Usually, your system will have a separate package for that. On Debian, it is called dovecot-dbg.

I can't readily reproduce it with the information available so far. Do you have the opportunity to obtain a GDB backtrace? You can e.g. run LDA manually at the command line with the same arguments and message input Postfix provides and wrap it in GDB if you can reproduce the crash.

Your configuration may also help (output from dovecot -n)

Do you have the opportunity to build Dovecot yourself, thereby including the debug symbols?

Hi Stephan,

I managed to get GDB, I hope this one helps. If not I can send the config too, but exactly same config works with 2.3.6.

You don't have the debug symbols for Dovecot installed. Usually, your system will have a separate package for that. On Debian, it is called dovecot-dbg.

That's a good thought.

I'm building from the alpine repo and I indeed see pigeonhole is 0.5.5

https://git.alpinelinux.org/aports/tree/main/dovecot/APKBUILD?h=3.8-stable

Let me build it with 0.5.7.2

Hi Stephan,

I managed to get GDB, I hope this one helps. If not I can send the config too, but exactly same config works with 2.3.6.

You don't have the debug symbols for Dovecot installed. Usually, your system will have a separate package for that. On Debian, it is called dovecot-dbg.

Thank you Stephan ! That was it.

It works fine with the proper pigeonhole version.

Let me write to the package maintainer to fix.

That's a good thought.

I'm building from the alpine repo and I indeed see pigeonhole is 0.5.5

https://git.alpinelinux.org/aports/tree/main/dovecot/APKBUILD?h=3.8-stable

Let me build it with 0.5.7.2

Hi Stephan,

Here it is:

We still can't reproduce it here.

First of all, did you update Pigeonhole along with Dovecot? This kind of weirdness can happen when Pigeonhole was compiled against a different version of Dovecot. You could compile Pigeonhole manually as well to make sure, which also gives you the opportunity to get debug symbols for Pigeonhole as well.

Do you also have your configuration for me (output from dovecot -n) ?

Also, can you issue in GDB after it crashed (as you did bt full before):

f 1 p src

Stephan.
